Filters Series UV1200, Lumped Elements Filters • • • • • 0.1 MHz to 6 GHz Low-Pass, High-Pass, Band-pass and BandStop Filters Standard Chebyshev, Generalized Chebyshev, Elliptic and Butterworth Types Linear Phase and Matched Phase Types (Optional) Small and Miniature Package Description Series UV1200 offers four main families of filters: Low-Pass, High-Pass, Band-Pass and BandStop. Standard lumped filters are implemented either by discrete or semi-lumped elements suitable for frequencies up to 6 GHz. Standard band-pass filters use either a Low-Pass-High-Pass series, a tubular equivalent design, a capacitor or inductor coupled tank design, or a modified Chebyshev or elliptic band-pass design. Various packages are available for selected insertion loss, skirt, and size. Standard packages include small and miniature cases. Special designs include: • • • • • • Combination of Chebyshev and Elliptic response, achieving steep skirt and monotonic rejection. Linear phase (constant group-delay) filters, using Gaussian or Bessel polynomials. Phase matched filters. Switched filters bank (by relays, PIN diodes or MMIC switches). Special packaging and connectors. Design to meet stringent airborne and naval military specifications. 12 Filters UV1200-1 and UV1200-2, Low-Pass and High-Pass Lumped Elements Filters Specifications Parameters Cutoff Frequency (1or 3 dB point) LPF: HPF: Insertion Loss Nominal Impedance VSWR Stopband Rejection Number of Sections Spurious-Free Range Average Input Power Specifications 0.5 to 6000 MHz 0.5 to 2000 MHz Refer to Tables 1 and 2, and paragraph b 50 ohms 1.5:1 maximum; DC to 90% of 1 dB cutoff frequency for Low-Pass filters, and 110% of 1 dB cutoff frequency to maximum spurious free frequency for High-Pass filters (refer to Table 3) See Figures 4 and 5; Refer to Table 3 and paragraphs a, b, and c 3 to 15; see Figures 4 and 5, and refer to paragraph a and Table 3 Refer to Table 3 1 to 5 W.

For example, a 300 MHz Low-Pass filter with 11 sections in an SM case has 50 dB minimum rejection from 405 to 1500 MHz (Figure 4). For High-Pass filters, spurious-free range is defined as the range where insertion loss specifications are maintained. For example, a 800 MHz High-Pass filter with 11 sections in a D case has a maximum insertion loss of 1.1 dB from 880 to 4000 MHz.

Calculating the Number of Sections The following procedure should be used to calculate the number of sections and the rejection (dB) of the desired filter. 1) Calculate the cutoff frequency FC (relative 1 dB point). 2) Select a frequency, FA, outside pass band where a specific attenuation, LA (dB) is required and find WL/H = FA/FC. 3) Calculate the number of sections (see Fig. 4 and Fig. 5), n, by setting WL/H on the horizontal axis and the required attenuation on the vertical axis. 14 Rejection (dB) Rejection (dB) Filters WL Figure 4. Rejection for Low-Pass Filters WH Figure 5. Rejection Curve for High-Pass Filters Consider a Low-Pass filter with the following characteristics: FC = 300 MHz at relative 1 dB point ; FA = 400 MHz for a stopband of 50 dB ; SM case 400MHz = 1.33 . It can be understood from Fig. 4 that the number of sections for 300MHz this value of WL and 50 dB attenuation is 11. In this case, WL = Note the data for the High-Pass filter below with the following characteristics: FC = 600 MHz at relative 1 dB point ; FA = 500 MHz for a stopband of 30 dB; D case 500MHz = 0.83 . From Figure 5, it can be determined that for this value of WH, 600MHz 30 dB attenuation can be obtained with 9 sections. In this case WH = b. Calculating Insertion Loss The maximum insertion loss is determined as follows: IL = LC(n+0.4) + 0.3 dB Where: IL = Insertion loss ; LC = Loss constant (given in Tables 1 and 2) ; n = number of sections (as obtained in paragraph a) This limit value of the insertion loss will be maintained from DC to 90% of 1 dB cutoff frequency for Low-Pass filters, and from 110% of 1 dB cutoff frequency to maximum spurious-free frequency for High-Pass filters (see Table 3). Using the numerical examples detailed above, in these cases the insertion loss is as follows: • • For the Low-Pass filter, IL = 0.08(11+0.4)+0.3 = 1.2 dB For the High-Pass filter, IL = 0.08(9+0.4)+0.3 = 1.0 dB from 660 MHz (110% of FC) up to 1800 MHz (see Table 3) c. Calculating Spurious-Free Range The frequency range in which the required rejection is maintained can be determined from Table 3. Refer again to the examples above. For the Low-Pass filter, 50 dB rejection is maintained on the frequency range 5 x FC = 5 x 300 MHz = 1500 MHz (identical top the upper limit for FC = 300 MHz). 15 Filters Example: UV1200-1-7-2100/7000-FS2, Miniature Low-Pass Filter, 2100 MHz Description This miniature lumped elements low-pass filter is based on an equal ripple Chebyshev polinomial, having a monotonic out-of-band rejection.

Calculating the Number of Sections Rejection curves for band-pass filters up to 30% bandwidth are described in Figure 6. For band-pass filters with 31 to 200% bandwidth, the low side and the high side skirts are treated separately as Low-Pass and High-Pass filters, respectively. The curves are depicted in Figures 7 and 8. The following procedure should be used to determine the number of sections of the desired filter: 3 to 30% Bandwidth 1) Calculate the center of frequency F0 = (FL + FH ) where FL and FH are the cutoff frequencies at 2 the lower and upper relative 3 dB points, respectively. 2) Calculate WB ± from WB ± = (Fatt − F0 ) BW where Fatt = Rejection frequency (MHz) ; F0 = Center frequency (MHz) ; BW = 3 dB relative bandwidth (MHz) 3) Determine the number of sections (see Figure 6), n, by setting the value of WB on the horizontal axis and the required attenuation on the vertical axis. Figure 6. Stopband Rejection (dBs) Curves for 3 to 30% Bandwidth 19 Consider a band-pass filter example with rejection curves from 3 to 30% of bandwidth and the following characteristics: FL = 200 Hz ; FH = 250 MHz ; BW = 50 MHz at relative 3 dB bandwidth ; Fatt = 150 and 300 MHz for a minimum stopband of 60 dB; SM case. In this case, F0 = (200 + 250) = 225 and thus Rejection (dB) Filters 2 300 − 225 = +1.5 and 50 150 − 225 = = −1.5 50 WB + = WB − WL Figure 7.

Refer to Table 9. 2) Select a certain frequency FAH at the higher side of the passband where a specific attenuation LAH F (dB) is required and find WL as WL = AH . FCH 3) Determine the number of sections (see Figure 7), nL, by setting WL on the horizontal axis, and the required attenuation on the vertical axis. 4) Determine the low cutoff frequency FCL (1 dB point) using Table 9. 5) Select a certain frequency FAL at the lower side of the passband where a specific attenuation LAL F is required, and find WH as WH = AL FCL 6) Determine the number of sections (see Figure 8), nH, by setting WH on the horizontal axis and the required attenuation on the vertical axis. 7) The number of sections is given by n = max (nL, nH). For example, consider a band-pass filter with rejection curves from 31 to 200% and the following characteristics: FCH = 500 MHz; FCL = 200 MHz; BW = 300 MHz at relative 1 dB bandwidth; Fatt = 100 and 700 MHz for a minimum 40 dB stopband Case C Using the equations above, it is determined that WL = 700/500 = 1.2 and WH = 100/200 = 0.5. Thus, by setting these values in Figures 7 and 8, respectively, it can be seen that for 40 dB attenuation, nL = 13 and nH = 7. Thus, n = 13. 21 Filters Table 8. 1 dB vs 3 dB Cutoff Frequency Ratio for up to 30% Bandwidth 2 3 4 to 8 0.65 0.8 0.85 Number of Sections Ratio Table 9. 1 dB vs 3 dB Cutoff Frequency Ratio for 31 to 200% Bandwidth Skirt Low Side Skirt High Side Skirt 3 Sections 5 Sections 7 to 19 Sections 0.65 1.50 0.85 1.15 0.90 1.10 Table 10.

Spurious-free range is defined as the range where a 50 dB minimum rejection specification is obtained for frequencies above the passband. b. Insertion Loss Determination The maximum insertion loss at center frequency (FO) is determined as follows: IL = LC (n + 0.4) + 0.3 BWR Where: IL = Insertion loss at FO in dB; LC = Loss constant (Tables 5 and 6); n = number of sections (as obtained in paragraph a); BWR = Percentage bandwidth obtained from: BW ×100% BWR = FO With reference to the examples given above, one can find that in these cases, the insertion loss is as follows: • For the band-pass filter with rejection curves from 3 to 30% of bandwidth 50 × 100% 3(6 + 0.4) BWR = = 22.22% and thus IL = + 0.3 = 1.2 dB . 225 22.22 • For the band-pass filter with rejection curves from 31 to 200% of bandwidth, 300 × 100% 3(13 + 0.4) BWR = = 85.7% and thus IL = + 0.3 = 0.8 dB . 350 85.7 22 Filters c. Estimating Band-Pass Group Delay Group time delay characteristics of the Chebyshev and/or Butterworth response filters can be approximated by the following: ΤF where Τd is the group time delay in nanoseconds and TF is the time 3 dB BW (MHz) factor at B, depicted in the group delay characteristics graph (Figure 9). Τd (nsc ) ) = The normalized radian frequency Ω is determined as follows: Ω = (Desired Frequency) − FO 3 dB BW For example: Find group delay at 530 MHz of a band-pass filter with the following characteristics: Number of sections (N) = 7; Center frequency (FO) = 500; 3 dB BW = 100 MHz Ω= 530 − 500 = 0.3 100 6000 5400 4800 3600 3000 2400 1800 Time Factor, TF 4200 1200 600 0 Normalized Radian Frequency, Ω Figure 9. Group Delay Characteristics Based on what is depicted in Figure 9 we find that for N = 7 and B = 0.3, TF = 2250 Using the equation for Τd it is understood that: Τd = 2250 = 22.5 ns at 530 MHz 100 Low-Pass filters may be observed at in a similar manner if zero frequency (DC) is considered FO and FCO is considered to be the upper 3 dB frequency (like a band-pass filter centered at zero frequency). 23 Filters Example: UV1200-3-6-650/120-E2, Miniature Band-Pass Filter, 590-710 MHz Description This miniature lumped elements band-pass filter is based on equal ripple Chebyshev polinomial, having a monotonic out-of-band rejection.
