Product Description

Features

The SGA5489Z is a high performance SiGe HBT MMIC Amplifier. A Darlington con-

figuration featuring one-micron emitters provides high F_Tand 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. Only two DC-blocking capacitors, a

bias resistor, and an optional RF choke are required for operation.
