Abstract
A phase shifter with temperature compensation for 28GHz phased-array TRX is presented. A precise low-voltage current reference is proposed for the IDAC biasing circuit. The total gain variation for a single TX path including phase shifter and post stage amplifiers over -40°C to 80°C is only 1dB in measurement and the overall phase error due to temperature is less than 1 degree without off-chip calibration.
