Skyworks has introduced its SKYA21038, SKYA21039, SKYA21040 and SKYA21041 for automotive, cellular compensator and cellular telematics.

The SKYA21038 is an SPDT switch aimed at mode switching in WLAN applications. Utilising advanced switching technologies, the device keeps low insertion loss and high isolation for all switching paths. The high-linearity performance and low insertion loss produced by the switch make it an excellent selection for low-power transmit/receive applications.

The SKYA21039 is an SP3T antenna switch that functions in the 2.4GHz to 2.5GHz frequency range. Switching between the antenna (RFC signal) and the RF1, RF2, and RF3 ports is achieved with two control voltages (V1 and V2). The low loss, high isolation, high linearity, small size, and low cost make this switch excellent for all WLAN and Bluetooth systems operating in the 2.4GHz to 2.5GHz band.

The SKYA21040 combines an SP3T switch and LNA with a bypass mode in an ultra-compact package. The device can switch between WLAN receive, WLAN transmit, and Bluetooth and is offered in a small DFN 8-pin, 1.5mm x 1.5mm package.


The SKYA21041 combines an SPDT switch and LNA with a bypass mode in an ultra-compact package. The device can switch between WLAN receive and WLAN transmit. It is offered in a small, six-pin, 1.2mm x 1.4mm DFN package.
