A Ku-Band Bi-Directional Transmit and Receive IC in 0.13 mu m CMOS Technology

초록

This paper presents a Ku-band transmit and receive IC in 0.13 mu m CMOS technology for mobile satellite communication beamforming systems. A Ku-band transmit and receive IC is composed of a bi-directional amplifier, a 6-bit phase shifter, and a 6-bit digital step attenuator. The precise trimming bits are implemented in the phase shifter (2.8 degrees) and digital step attenuator (0.5 and 1 dB) for the amplitude and phase error correction. The phase variation range of the phase shifter is 360 degrees with a phase resolution of 5.625 degrees. The attenuation range of 31.5 dB with an amplitude resolution of 0.5 dB is achieved. The gain of 2 similar to 5 dB and the input/output return losses of >10 dB are achieved from 12 to 16 GHz. The chip size is 2.5 x 1.5 mm(2) including bonding pads. The DC power consumption is 216 mW.
