摘要

We demonstrate a new MMIC smart power amplifier, dual chain power amplifier with single matching network, of which power added efficiency (PAE) for 16 dBm output power is as much as 21%, which represents more than a factor of three improvement of the PAE while satisfying all W-CDMA specifications. The power amplifier has been devised with two different parallel connected InGaP/GaAs HBT power amplifiers, each of amplifier is fined to different maximum power value: one to 17.5 dBm for low power mode and the other to 28 dBm for high power mode. The low power mode reveals -33dBc of adjacent channel leakage power ratio (ACLR) at 16 dBm with 14mA of quiescent current. The high power mode exhibits 40% of PAE and -30dBc of ACLR at the maximum output power of 28dBm.
