Dual-Band Matched SP4T Wi-Fi Switch
Available from Skyworks
Skyworks offers a dual-band single-pole four-throw (SP4T) WiFi switch with integrated GPIO interface and 50 Ohm match on all RF output ports.
The new SKY13575-639LF is ideal for dual-band switching in Wi-Fi access points, WLAN 802.11ac and 3G/4G LTE systems and is also suitable for access points, customer-premises equipment (CPE), LTE systems, dual-band WLAN and test and measurement equipment. Using SOI technology, the switch consumes less than 10 µA of current and offers customers broad frequency range, low loss and high isolation characteristics and integrated match*. The built in decoders also simplifies the process for customers because it limits the number of GPIO lines needed for control. SKY13575 can operate over the temperature range of -40 °C to 90 °C which makes it suitable for a variety of applications. The switch boasts a small footprint, and is delivered in a 14-pin, quad-flat no-lead (QFN) 1.6 x 1.6 x 0.45 mm package.
*The SKY13575-639LF performs with low insertion loss (0.6 dB at 2.5 GHz, 1.1 dB at 6 GHz) and high isolation (40 dB at 2.5 GHz, 30 dB at 6 GHz).
