YSOS001AA Single Pole Quad Throw RF Antenna Tuner

The YSOS001AA is a single pole quad throw (SP4T) RF antenna aperture switch optimized for low COFF enabling applications up to 6.0GHz. This single supply chip integrates on-chip CMOS logic driven by a simple, single-pin CMOS or TTL compatible control input signal. Unlike GaAs technology, the 0.1dB 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.
