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 RΘ 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.
