High RF voltage dual SPST antenna aperture shunt switch

The BGSA20UGL8 is a versatile Dual Single-Pole Single-Throw (SPST) RF antenna shunt aperture switch optimized for low COFF as well as low RON enabling applications up to 6.0 GHz. This single supply chip integrates 2 digital control pins. Unlike GaAs technology, the 0.1 dB compression point exceeds the switch maximum input power level, resulting in linear performance at all signal levels and external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally. Due to its very high RF voltage ruggedness, it is suited for switching any reactive devices such as inductors and capacitors in RF matching circuits without significant losses in quality factors.
