Abstract :
A novel monolithic 5-b phase-shifter topology made realizable by the use of PIN diode switching elements has demonstrated lower insertion loss than that available from more conventional configurations. The phase shifter features predicted insertion loss <3.0 dB and VSWR (voltage standing wave ratio) <1.6:1 over the 20% frequency band in the X-band region. Monolithic chips have been fabricated and evaluated. The experimental results presented indicate that these performance goals are achievable.<>
