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.

5G NR相控阵收发器的温度补偿28GHz移相器

提出了一种用于28GHz相控阵TRX的温度补偿移相器。针对IDAC偏置电路，提出了一种精确的低压电流基准。在-40°C至80°C范围内，单个TX路径(包括移相器和后级放大器)的总增益变化在测量中仅为1dB，并且在没有片外校准的情况下，由于温度引起的总体相位误差小于1度。
