Abstract :
A UHF-band 1.3-W high-efficiency, four-stage monolithic power amplifier with a novel miniaturized second-harmonic terminating circuit was developed. With the use of a parallel resonant circuit composed of lumped elements for terminating the second harmonic, it achieved a maximum drain efficiency of 63% and a saturated output power of higher than 31 dBm in the UHF band, and it occupied an area of 8.6*5.8 mm.<>
