SPDT RF switch suits WLAN 802.11 applications
A Single-Pole, Double-Throw (SPDT) RF switch from pSemi is now available at distributor RFMW.
With operating range from 100 to 8500 MHz, the PE42424 reflective 50 Ohm SPDT RF switch supports bandwidths up to 6 GHz.
Designed for use in high power and high performance WLAN 802.11 a/b/g/n/ac applications such as carrier and enterprise Wi-Fi products, the PE42424 provides up to 48 dB port-to-port isolation, 145 nS switching time and can handle 1 Watt of CW power (39 dBm pulsed), all in a compact, 1.5 x 1.5 mm package.
IIP2 linearity of 125 dBm guarantees throughput that remains invariant over the full power supply range.
The switch does not require blocking capacitors or any external matching components.
