A Ku-band phased-array transceiver using 0.13- μm SiGe BiCMOS technology is proposed in this paper for satellite communication applications. With a 6-bit inductive compensated attenuator and a 6-bit phase shifter integrated in the common-leg of the receive (RX) and transmit (TX) paths, the transceiver realizes 6-bit phase and attenuation control of the RF signal. The transceiver realizes larger than 20 dB gain, with RMS gain/phase error less than 1 dB/10° within 16-18 GHz. The whole transceiver occupies 2.7 × 2.5 mm2 chip area.
