Description
The CMM0336 is a highly efficient linear 6 V, multi-
mode power amplifier intended for use in portable cellular
handsets and datacom products operating in the AMPS and
902-928 MHz bands. As a pin-compatible member of the new
Triniti DX™ amplifier family, the CMM0336 offers maxi-
mum performance and flexibility. The CMM0336 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, simplify-
ing design and keeping board space and cost to a minimum.
