RF Switches

Skyworks offers a broad range of RF switches for a variety of applications, including automotive, high power, Wi-Fi switching, and IoT signal control. Automotive switches (SKYA) include longer life cycles, high power switches covering up to 160 watts. From small form factor IoT switches to high isolation switches that maximize signal differentiation and high throw count switches enabling multiplexing for many signals, all Skyworks Wi-Fi switches meet the rigorous specs associated with the latest industry standards.

Automotive Switches

Skyworks’ automotive RF switches are ideal for applications including infotainment, RKE, e-call, cellular compensator and feature support for PPAP, longer product life cycles, and, in some cases, include full AEC-Q100 qualification. With available options including SP2T, SP3T, and DPDT, these automotive switches are designed to optimize power handling for a variety of scenarios from low power at sub 20 dBm, medium power at 23 dBm, and high power at above 30 dBm.

High Power Switches

Designed for infrastructure, 5G, base stations, and military radio fail safe transmit and receive, Skyworks PIN diode SP2T switches feature power handling on TX from 40 watts to 160 watts with frequency coverage from 50 MHz to 5 GHz, depending on the particular product. These cost-effective PIN diode-based switches are designed with the lowest insertion loss and highest isolation to minimize transmission losses and protect receivers and lowest current consumption. Their QFN packages with exposed paddles maximize heat transfer and minimize PCB footprint.

Skyworks FET-based SP2T and DPDT switches are designed to support LTE and GSM signals with low insertion loss and high isolation and are offered in small surface mount packages for size-constrained modules.

Wi-Fi Switches

Skyworks’ Wi-Fi switches are used to switch between transmit and receive signals or selection between main and diversity antennas. Skyworks’ broad portfolio of SPDT, SP3T, and DPDT switches are designed for fast switching with minimum insertion loss to meet the high data throughput of applications such as routers, gateways, set-top boxes, wireless audio/video. Their high linearity making them an excellent choice for the high modulation rates associated with today’s radios, while their plastic surface mount packaging helps keep costs to a minimum.

IoT Switches

Skyworks’ IoT switches cover a broad range of applications, including smart cities, medical, smart homes, and wearables. Many of Skyworks’ IoT switches are specified for operation to industrial temperatures of 105°C and are available with frequency coverage from 20 MHz on the low side to 8 GHz on the high side. These IoT switches cover low power in leaded packages for ease of soldering to high power in QFN packages with exposed paddles for more stringent thermal requirements.

High Isolation Switches

Skyworks offers several SPDT switches designed with isolation as the top priority, making them ideal for cellular infrastructure, test and measurement, RFID and military communications applications. This family includes two products with 50 ohm terminations to maintain a good match in the isolated port with isolation as high as 60 dB at 3 GHz.

High Throw Count Switches

For switching in different filters or to select between multiple antennas, Skyworks’ family of switches includes a variety of high throw count switches with anywhere from 4 to 10 throws. Equipped with multiple arms, these high throw count switches are ideal for creating multi-band matrix switches. Featuring low loss, high isolation, and excellent linearity, they are best for transmitting and receiving radio signals with minimum disturbance. Selection of the switching may be done with either GPIO or standard MIPI commands.
