A single-stage RF programmable gain amplifier (RF-PGA) in 65-nm CMOS is presented. The RF-PGA consists of thermometer-weighted transconductors and binary-weighted transconductors with an R-2R ladder. The transmitter prototype with the single-stage RF-PGA achieves 78 dB dynamic range, 0.27 dB accuracy in 1dB step at 1950 MHz. The measured transmitter noise in RX band is −160.4 dBc/Hz. The ACLR and EVM with LTE modulated signal (BW=20 MHz) are −40 dBc and 3.4 %, respectively.
