New SP4T Switch For WiFi Covers 100MHz to 6GHz

RFMW has announced a dual-band SP4T (single-pole, four-throw) switch developed for WiFi applications in the 2.4 and 5GHz ISM bands. The new Skyworks SKY13575-639LF supports access points and CPEs along with WLAN test and measurement equipment.

The switch covers frequency range from 100MHz to 6GHz with a maximum insertion loss of 1.4dB. Isolation ranges from 26 to 40dB and the switch handle up to 32dBm of input power for demanding applications.

Switching is controlled by two CMOS/TTL compatible control voltage inputs: VC1 and VC2. Depending upon the logic voltage level applied to the control pins, the RFC pin is connected to one of four switched RF outputs (RF1 to RF4) by a low insertion loss path, while the path between the RFC pin and the other RF pins is in isolation. The isolated ports are terminated to a 50 ohm load.

Additional key features include a current consumption of less than 10 micro amps using SOI technology. Built-in decoders limit the number of GPIO lines needed for control and internal matching eases design considerations.

The switch can operate over the temperature range of -40 deg C to 90 deg C, and offered in a tiny, 14-pin, 1.6 x 1.6 x 0.45mm QFN package.
