The CMM1321 offers maximum performance and flexibility. The amplifier is designed to support the requirements of PCS CDMA (ANSI .. J-STD-018) systems. The CMM1321 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 and matching, simplifying design and keeping board space and cost to a minimum. Through matching adjustment, equivalent performance can also be achieved for the 1.93 to 1.99 GHz PCS bands as well as the 1.6 GHz satellite bands.
