A new low cost phase shifter for land mobile satellite transceiver

This paper describes the design of a new low cost analog single stage phase shifter for affordable phased array antennas for mass-market land mobile satellite transceiver. A linear phase shift of more than 360-degree in Ku (12.2-12.7 GHz) band with less than 4.0 dB insertion loss is achieved. The phase shifter is composed of 3-dB hybrid coupler, novel compact reflective terminating loads and hyperabrupt junction varactor diodes. The effect of insertion loss variation of this phase shifter over noise figure of cascaded LNA is also studied and measured.
