The Design of a Low Loss, High Power, Microwave Switch MMIC
نویسندگان
چکیده
This paper describes the development of a low loss, high power, microwave switch MMIC design. The operating bandwidth of the switch was 7 to 11GHz. Simulated performance shows an insertion loss of 0.71dB at mid-band rising to 0.85dB at the band-edge. The estimated power handling capability of the switch is 6.3W at 1dB compression for 0/-10V control. Isolation is better than 27dB across the entire band and the worse-case return loss is 16dB. The design was undertaken using the FD05 0.5μm gate length PHEMT process from Filtronics, which means that the resultant switches would be available from a UK supplier.
