摘要
A single-chip linear power amplifier (PA) with > 48-dB gain control range and > 24-dBm output power with adjacent channel leakage power below -36 dBc is presented. The chip is realized using an AlGaAs/GaAs heterojunction-bipolar-transistor process and is aimed for 1.95-GHz mobile WCDMA applications. The amplifier consists of two blocks, the variable-gain amplifier, and the PA. The chip size is 1.3 x 1.1 mm(2) and it is mounted on an 8 x 8 mm(2) FR-4 type laminate with 26 pieces of 0402 Surface-mountable discrete components composing a complete 50-Omega input-output amplifier module. This paper presents the design of the two blocks, discusses issues related to their combining, and presents complete amplifier realization and measurement results.
