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 sys-
tems. 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 RΘ of less than 18° 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.
