Package: SOT-89
Product Description
The SGA7489Z is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring one-micron emitters provides high FT and excellent thermal performance. 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.
