Broadband single pole four throw (SP4T) switches in coplanar (CPW) waveguide based on cantilever or clamped - clamped switches have been developed for use in space application. All the devices are manufactured on high-resistive silicon using surface micro-machining technology. The SP4T switches provide very good performance in terms of insertion and return loss and isolation over a wide frequency band. These switches are intended to be used as building block for large order switching matrices for satellite applications. Full wave simulations as well as measured RF performances are reported. The two are in a very good agreement, showing high performance for all SP4T typologies. Depending on the specific design, insertion loss between 0.5 and 1.25dB, return loss between 20dB and 26dB and isolation between 35dB and 50dB has been obtained in the 0-6 GHz frequency band.

Abstract

Broadband single pole four throw (SP4T) switches in coplanar (CPW) waveguide based on cantilever or clamped - clamped switches have been developed for use in space application. All the devices are manufactured on high-resistive silicon using surface micro-machining technology. The SP4T switches provide very good performance in terms of insertion and return loss and isolation over a wide frequency band. These switches are intended to be used as building block for large order switching matrices for satellite applications. Full wave simulations as well as measured RF performances are reported. The two are in a very good agreement, showing high performance for all SP4T typologies. Depending on the specific design, insertion loss between 0.5 and 1.25dB, return loss between 20dB and 26dB and isolation between 35dB and 50dB has been obtained in the 0-6 GHz frequency band.
