Abstract: A 360?broad-band analog phase shifter is designed by means of CAD. Linear phase-shift, balancing insertion loss and expanding bandwidth of phase shifter are analyzed in detail. The objective function about phase shifter s bandwidth is also deduced. The analog phase shifter which uses hyperabrupt varactor chips is fabricated with MIC technology. In the frequency range of 1.3-2.1GHz, continuous variable phase-shifter up to 360 and linear deviation of less than 2.5% can be obtained. Its insertion loss varies less than 3dB. Comparing with reported phase shifters, its performances are excellent. -
