SGA6289Z

DC to 4500MHz, CASCADABLE SiGe HBT

MMIC AMPLIFIER

The SGA6289Z is a high performance SiGe HBT MMIC Amplifier. A Darling-

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 intermodu-

lation products. Only two DC-blocking capacitors, a bias resistor, and an

optional RF choke are required for operation.
