8 TO 12 GHz IMAGE REJECTION OR I/Q MIXERS
MODELS: IR0812LC2A, IRO812LC2B, IRO812LC2C AND IRO812LC2Q FEATURES • RF/LO Coverage ............ 8 to 12 GHz • IF Operation .................. DC to 0.5 GHz • LO Power Range ............ +10 to +13 dBm • Conversion Loss ............. 6.5 dB Typical • Image Rejection ............. 23 dB Typical
MITEQ’s IR series of image rejection mixers is useful for wideband test equipment or in ultra-broadband receivers requiring rejection of an unwanted sideband of signal or noise following a low-noise front-end amplifier. These mixers are also useful as linear single-sideband upconverters by operating in the reverse mode. Higher RF input power versions are available with proportional increases in LO power. Greater image rejection is also available in selected bandwidths, including the IRE series for the 2 to 8 and 6 to 18 GHz bands.
