Description

The CMM2321 is a power amplifier intended for use

in 2.4 GHz ISM band applications such as wireless datacom

equipment, wireless bar code scanners and inter-building cam-

pus networks. This flexible amplifier can be biased to support

the requirements of frequency hopping or direct sequence sys-

tems. The CMM2321 is packaged in a low-cost, space effi-

cient SO-8 power package that gives excellent electrical sta-

bility and thermal handling performance with a R

of less

than 18° C/W. The part is designed to require minimal exter-

nal circuitry for bias matching, simplifying design and keep-

ing board space and cost to a minimum.
