High Performance SOI RF Switch for Healthcare Application

The objective of this research was to design a 0-5 GHz RF SOI switch, with 0.18um power Jazz SOI technology by using Cadence software, for health care applications. The ultimate goal for such application is minimize the trade-offs between performance and cost, and between performance and low power consumption design. This paper introduces the design of a RF switch implemented in shunt-series topology. An insertion loss of 1.36 dB and an isolation of 58.5 dB were obtained at 5 GHz. The switch also achieved a third order distortion of 57.12 dBm and 1 dB compression point reached 38.83 dBm. The performance of the RF switch meets the specification requirements of the desired.
