Description
The CMM1321 is a 5 V linear power amplifier
intended for use in PCS handsets, wireless local loop sub-
scriber units and PCS base stations. The CMM1321 offers
maximum performance and flexibility. The amplifier is
designed to support the requirements of PCS CDMA (ANSI
www.DataSheet4U.com J-STD-018) systems.
The CMM1321 is packaged in a low-cost, space effi-
cient SO-8 power package that gives excellent electrical stabili-
ty and thermal handling performance with a RΘ of less than
18° C/W. The part is designed to require minimal external cir-
cuitry for bias and matching, simplifying design and keeping
board space and cost to a minimum. Through matching adjust-
ment, equivalent performance can also be achieved for the 1.93
to 1.99 GHz PCS bands as well as the 1.6 GHz satellite bands.
