Description
The CMM0330 is a highly efficient 3 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 CMM0330 offers maximum performance
and flexibility. The CMM0330 is packaged in a low-cost,
space efficient SO-8 power package that gives excellent elec-
trical stability and thermal handling performance with a R_Θ 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.
