SGA-6589
Product Description
DC-3500 MHz, Cascadable SiGe HBT MMIC Amplifier
Sirenza Microdevices SGA-6589 is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring 1 micron emitters provides high F T and excellent thermal perfomance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. At 850 Mhz and 80mA , the SGA6589 typically provides +32.5 dBm output IP3, 25.5 dB of gain, and +21.5 dBm of 1dB compressed power using a single positive voltage supply. Only 2 DC-blocking capacitors, a bias resistor and an optional RF choke are required for operation.
