We present the design and development of a novel integrated multiband phase shifter that has an embedded distributed amplifier for loss compensation in 0.18-m RF CMOS technology. The phase shifter achieves a measured 180 phase tuning range in a 2.4-GHz band and a measured 360 phase tuning range in both 3.5-and 5.8-GHz bands. The gain in the 2.4-GHz band varies from 0.14 to 6.6 dB during phase tuning. The insertion loss varies from 3.7 dB to 5.4-dB gain and 4.5 dB to 2.1-dB gain in the 3.5-anddoi:10.1109/tmtt.2005.860892 fatcat:jdaftrm3qzfd7ni4o7nn6jiuyq
