Abstract

Poor quality, low cost PIN diodes have been used to design a 4-bit phase shifter for possible use in an electronically steered, vehicle mounted mobile satellite antenna system. These diodes can not operate as good on-off switches and therefore cannot be directly incorporated in the standard phase shifter configurations. Their performance can be improved by tuning out the parasitic elements over the required frequency band by including LC compensation circuits in their biasing networks. Series and parallel switches were developed for the required loaded line and switched line phase shifters. The developed 22.5°, 45°, 90° and 180° phase shifters have shown superior performance despite the use of low quality diodes.
