Abstract
A high-linearity and high-efficiency MMIC power amplifier is proposed that adopts a new on-chip adaptive bias circuit, which simultaneously improves efficiency at the low output power level and linearity at the high output power level. The intelligent W-CDMA power amplifier using the adaptive bias circuit extends the maximum linear output power of 0.6 dB and exhibits an improvement of average power usage efficiency of 1.85 times.
