Product Description
The SGA3286Z is a high performance SiGe HBT MMIC Amplifier. A Darlington con-
figuration featuring one-micron emitters provides high F_T and excellent thermal per-
formance. 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 850MHz and 35mA, the
SGA3286Z typically provides +12.2dBm of 1dB compressed power using a single
positive voltage supply. Only two DC-blocking capacitors, a bias resistor, and an
optional RF choke are required for operation.
