Product Description
Sirenza Microdevices SGA-2286 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
20mA , the SGA-2286 typically provides +20 dBm output IP3,
15.0 dB of gain, and +8.3 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.
