Abstract
A MMIC SiGe HBT balanced power amplifier for cdma2000 is proposed. The PA delivers 28.5 dBm linear output power with an adjacent channel power ratio ACPR below -44 dBc, a PAE of 35% and a gain of 30 dB. Thanks to the balanced approach without the use of an isolator, the PA under a 4:1 VSWR load mismatch delivers 26 dBm linear output power with a 1.5 dB gain variation and a 15% current consumption increase. The PA has been realized by using a 0.25 /spl mu/m BiCMOS technology.
