Single-Pole Switches: SKYA21038, SKYA21039
The SKYA21038 from Skyworks is a single-pole, double-throw (SPDT) switch. The SKYA21039 is a single-pole, dtriple-throw (SP3T) switch. Both switches have integrated DC blocking capacitors, so external DC blocking capacitors are not required.
SKYA21038 operates in the 0.9 to 6.0 GHz frequency range and is intended for mode switching in WLAN applications. Using advanced switching technologies, the SKYA21038 maintains low insertion loss and high isolation for all switching paths.
The SKYA21039 operates in the 2.4 to 2.5 GHz frequency range. Switching between the antenna (RFC signal) and the RF1, RF2, and RF3 ports is accomplished with two control voltages (V1 and V2). The low loss, high isolation, high linearity, small size, and low cost make this switch ideal for all WLAN and Bluetooth systems operating in the 2.4 to 2.5 GHz band.
