The SKY19243-686LF from Skyworks is an SPDT antenna tuning switch that operates from 0.1 to 3.8 GHz. It has a high linearity low insertion loss and can handle 40 dBm of power. Switching is controlled by an integrated GPIO interface with two control pins. Depending on the logic voltage level applied to the control pins, the antenna port can be either connected to one of the two switched RF outputs or to both switch outputs simultaneously. No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path. It is available in a compact 10-pin, 1.5 x 1.1 x 0.5 mm QFN package that meets requirements for board-level assembly. This switch is ideal for antenna tuning, Impedance tuning and band switching.
