United Monolithic Semiconductors CHA3063-99F-00 Datasheet

5.5-23GHz Driver Amplifier

GaAs Monolithic Microwave IC

Description

The CHA3063 is a two-stage general
purpose monolithic medium power
amplifier.The back side of t he chip is both RF
and DC grounds.This helps simplify the
assembly process.

The circuit is manufactured with a PM­HEMT process : 0.25µm gate length, via
holes through the substrate, air bridges and
electron beam gate lithogr aphy.
It is supplied in chip form.
