SGA4563Z

DC to 2500MHz, CASCADABLE SiGe HBT

MMIC AMPLIFIER

Package: SOT-363

Product Description

Features

The SGA4563Z is a high performance SiGe HBT MMIC Amplifier. A Darling-

ton configuration featuring one-micron emitters provides high F_Tand

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.
