United Monolithic Semiconductors CHA5215aFKF-23, CHA5215a99F-00 Datasheet

Description

CHA5215a

5.8GHz Medium Power Amplifier

GaAs Monolithic Microwave IC

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 thank s
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 packag e.

Main Features

■ Wide operating frequency range

■ High saturated output power

■ High linearity

■ High gain

■ High dynamic gain control

■ Output power monitor

■ Chip dimensions : 2.47 x 1.27 x 0.10 mm
