A 4-bit wideband distributed phase shifter has been developed for Ka-band operation. The design results show that the digital shifter has four basic phases of 11.25o, 22.5o, 45o, 90o and thus 16 kinds of phase states can be constructed from the combination of them. The simulation results also demonstrates that the insertion coefficient is better than -1.37 dB, the phase error is less than 3.983o at 30GHz, and the reflection coefficient is lower than -10dB from 25GHz to 35GHz for each state. This low-loss distributed metal-air-metal MEMS phase shifter can be well applied to phased arrays.
