0.1 to 3.0 GHz SP3T Switch

The SKYA21002 is a single-pole, triple-throw (SP3T) antenna switch that operates in the 0.1 to 3.0 GHz frequency range. Switching between the antenna (RFC signal) and the RF1, RF2, and RF3 ports is accomplished with three control voltages.

The low loss, high isolation, high linearity, and small size make this switch ideal for all WLAN and Bluetooth® signals operating in the 2.4 to 2.5 GHz band.

The switch is manufactured in a compact, 2 x 2 mm, 8-pin Dual Flat No-Lead (DFN) package.
