A 24.2-30.5GHz Quad-Channel RFIC for 5G Communications including Built-In Test Equipment

A wideband quad-channel beamforming RFIC for worldwide 5G infrastructure applications in 130nm SiGe BiCMOS features an Rx single channel gain and NF of 22 and 4dB respectively at a total power consumption of 1.6W. Tx performance includes a P1dB of 18dBm CW and 11.5dBm RMS output power at 3% EVM and 1.8W total power consumption. Beamforming is based on a temperature invariant lumped true time delay and a phase invariant programmable gain amplifier. Integrated built-in test equipment including LO-generation, signal injection and detection enables low-cost RF production testing and array calibration.
