Skyworks RF Switch Distributor | SPDT and SP3T Switches
Genuine Skyworks SPDT and SP3T RF switches for antenna routing, band selection and transmit/receive paths.
Skyworks RF Switches Overview
BeiLuo supplies genuine Skyworks RF switches, the SOI and GaAs devices that route signals between antennas, filters and radio paths. A switch connects the radio to the correct antenna or band, and its insertion loss and isolation set how much signal is lost on the wanted path and how much leaks onto the unwanted path. Skyworks switches cover single-pole double-throw and single-pole triple-throw configurations across bands from 100 MHz to 8 GHz, with low insertion loss, high linearity and good power handling, which makes them suitable for everything from smartphones and Wi-Fi radios to infrastructure and test equipment. Because they are built in silicon-on-insulator or GaAs processes, they combine fast switching with low control current, and they are available in compact QFN packages that fit dense boards. The choice between configurations and frequency ranges is driven by the number of paths a design must select and the band it operates in, and the switch is usually paired with a front-end module or an LNA. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you match the switch to your band, power and control scheme and verify the RF layout.

Frequently Asked Questions
How do insertion loss and isolation affect my design?
Insertion loss adds directly to the loss of the wanted path, so it reduces range and efficiency. Isolation determines how much signal leaks onto the unwanted path, so it limits how well bands and paths are separated.
Both matter, and the best switch balances them against cost and size.
Should I choose SPDT or SP3T?
Use SPDT when you need to select between two paths, such as transmit and receive, and SP3T when a design must choose among three, such as three antennas or three bands.
Choose the simplest configuration that covers your routing needs.
What control scheme do these switches use?
Skyworks switches use standard logic control voltages, with low control current, so they interface directly to a baseband or radio controller.
Confirm the control levels and timing against your system before layout.
