Abstract: A 10-200 MHz wideband 360° phase control vector-sum phase shifter (VSPS) is presented. Broadband VSPS are commonly implemented in IC technologies for microwave frequencies. By using commercial-off-the-shelf (COTS) discrete components on PCB, a wideband VSPS design is proposed and experimentally demonstrated. An RMS phase error of less than 1.5°, input return loss larger than 15 dB and amplitude imbalance less than 1 dB are measured from 10 to 100 MHz. An RMS phase error of about 5°, a return loss around 10 dB and amplitude imbalance less than 2.5 dB are measured from 10 to 200 MHz. The board dimension is 8.4cm × 7.8cm. © 2013 IEEE.
