A WR3-Band 2-bit Phase Shifter Based on Active SPDT Switches

The design and performance of a compact WR3-band 2-bit phase shifter manufactured in a 35-nm InGaAs technology are described. To compensate the loss of the phase shifting networks, active single-pole double-throw switches are embedded. The 180° and 90° phase shifting networks are based on a broadsid...

Zusammenfassung:The design and performance of a compact WR3-band 2-bit phase shifter manufactured in a 35-nm InGaAs technology are described. To compensate the loss of the phase shifting networks, active single-pole double-throw switches are embedded. The 180° and 90° phase shifting networks are based on a broadside-coupled 1:1 magnetic transformer and a hybrid edge-coupled tandem coupler, respectively. Measurements show a maximum gain of 0.22 dB with a 3-dB bandwidth of 44 GHz ranging from 235 to 279 GHz. Root-mean-square gain and phase errors are below 0.18 dB and 2.8°, respectively.
