Test Conditions:

Sirenza Microdevices’ SGA-6289 is a high performance SiGe

HBT MMIC Amplifier. A Darlington configuration featuring 1

micron emitters provides high F

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 75mA , the SGA-

6289 typically provides +34.4 dBm output IP3, 13.9 dB of gain,

and +18.1 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.
