摘要

A GaAs MCM power amplifier has been developed for 1.9-GHz digital cordless telephones. Power-added efficiency of 40.2% and P/sub 1dB/ of 22.2 dBm have been obtained at drain supply voltage of 3.6 V. Adoption of the MCM structure and on-chip ferroelectric capacitors has successfully reduced the GaAs total chip area to be 1.1 mm/sup 2/.
