Switching between the antenna and Tx/Rx ports is accomplished with 3 control inputs. When the control inputs are driven with the appropriate voltages, a low insertion loss path is provided from an antenna port to an Rx or Tx port, while the other ports have high attenuation. Skyworks offers lead (Pb)-free, RoHS (Restriction of NEW Hazardous Substances)-compliant packaging.
