PG175TA

L-Band PA DRIVER AMPLIFIER

DESCRIPTION

PG175TA is a GaAs MMIC for PA driver amplifier with variable gain function which was developed for PDC

µ

(Personal Digital Cellular in Japan) and another L-band application. The device can operate with 3.0 V, having the
high gain and low distortion.
