Product Description
Sirenza Microdevices’ SGA-4286 is a high performance SiGe
HBT MMIC Amplifier. A Darlington configuration featuring 1
micron emitters provides high FT 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 45mA , the SGA-
4286 typically provides +29.1 dBm output IP3, 13.5 dB of gain,
and +15 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.
