1920CD60
60 Watts PEP, 25 Volts, Class AB
CDMA Personal 1930 - 1990 MHz
GENERAL DESCRIPTION CASE OUTLINE
The 1920CD60 is a COMMON EMITTER transis t or capable of providing 60
Watts of Class AB, RF PEP output power over the band 1930-1990 MHz.
This transistor is specifically designed for LINEAR PERS O NAL (PCS)
CDMA CO M M UNICATI O NS BAS E STATIO N amplifier applications. It
includes two stage input and single output prematching. It utilizes Gold
meta l i zat i on an d EM ITTER ball a s t i n g to provide hi gh re l iab ility and
supreme ruggedness.
