Description
The CMM1330 is a 3V linear power amplifier
intended for use in PCS handsets, wireless local loop sub-
scriber units and PCS base stations. As a pin-compatible
member of the new Triniti DX™ amplifier family, the
CMM1330 offers maximum performance and flexibility. The
flexible amplifier can be biased to support the requirements
stability and thermal handling performance with a R of less
Θ
than 18° C/W. The part is designed to require minimal exter-
nal circuitry for bias matching, simplifying design and keep-
ing board space and cost to a minimum.
