Description

The CMM0335 is a highly efficient, 6V power
amplifier intended for use in portable cellular handsets and
datacom products operating in the SMR, GSM and 902–928
MHz ISM bands. As a pin-compatible member of the new

Triniti DX

™ amplifier family, the CMM0335 offers maxi-

mum performance and flexibility.The CMM0335 is packaged
in a low-cost, space efficient SO-8 power package that gives
excellent electrical stability and thermal handling performance
with a RΘof 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.
