Product Description
Features
The SGA5489Z is a high performance SiGe HBT MMIC Amplifier. A Darlington con-
figuration featuring one-micron emitters provides high FT and excellent thermal per-
High Gain: 17.9dB at

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.
