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 0.7m 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.
