摘要
A 60 GHz passive phase shifter with low phase and amplitude error is presented in this paper. Unlike other passive phase shifter, this phase shifter consists of 2 switch type phase shifter (STPS), vector generator and vector selector to achieve 4 bit (22.5 degrees phase resolution) and full 360 degrees phase synthesizing. From 57-66 GHz, the measured insertion loss is 17 dB. The RMS phase and amplitude error are < 5 degrees and 0.5 dB, respectively, and the gain flatness is +/- 0.5 dB with no dc consumption. The total chip size is 0.168 mm(2). Beside, this phase shifter can operate without extra digital to analog convertor (DAC). To the authors knowledge, this phase shifter demonstrate the lowest
