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
of PCS-1900, IS-136, or DCS-1800 systems.
The CMM1330 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 exter-
nal circuitry for bias matching, simplifying design and keep-
ing board space and cost to a minimum.
