CHA5215A Datasheet, PDF (1/12 Pages) United Monolithic Semiconductors – 5.8GHz Medium Power Amplifier

CHA5215a
5.8GHz Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA5215a is a MMIC multifunction
integrating a 3-stage medium power
amplifier, a gain control and an output
detector. A high saturated output power
allows a linear operating point for
multichannel communication applications.
The output power can be controlled thanks
to the combination of a detected output
voltage and an important gain control
dynamic range.
The circuit is manufactured with a standard
0.7µm implanted power MESFET, air
bridges, via holes through the substrate
and electron beam gate lithography
process. It is supplied in chip form or in
ceramic flat-pack package.
