Abstract
A highly linear HBT power amplifier (PA) for LTE-A small-cell base-stations is presented. By separating a bias point of the PA sub-cells and combining these outputs with out-of phasing, the third-order intermodulation distortion (IMD) can be reduced. By the simulation results, the third-order IMDs are approximately -50 dBc and -43 dBc with and without the separate biasing at an output power of 29 dBm, respectively. The designed HBT PA has a gain of 31 dB, a P1dB of 35 dBm, and a PAE of 38.1% under 5 V supply voltage.
