Abstract

This paper presents a T/R (transmit/receive) module for Ka-band phased arrays using a 0.12μm SiGe BiCMOS process. The T/R module consists of a low noise amplifier (LNA), power amplifier (PA), 4-bit phase shifter, and single-pole-double-throw (SPDT) switches. The LNA and PA are implemented using SiGe HBTs, and the phase shifter and SPDT switches are based on CMOS switches. The LNA achieves 23.5dB gain and 2.9dB noise figure at 34GHz. The 42% fractional-bandwidth PA has a small-signal gain of 13dB and a saturated output power of 19.4dBm with 11.2% PAE from 32 to 33GHz. The RMS phase error of the 4-bit phase shifter is less than 7.5° from 30-38GHz. This paper presents the individual components of the BiCMOS T/R module, and the entire T/R module performance will be measured and presented at the conference.
