General 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 campus networks. This
flexible amplifier can be biased to support the requirements of
frequency hopping or direct sequence systems. The CMM2321 is
packaged in a low-cost, space efficient SO-8 power package that
gives excellent electrical stability and thermal handling
performance with a R of less than 18º C/W. The part is designed
to require minimal external circuitry for bias matching, simplifying
design and keeping board space and cost to a minimum.
