Peregrine Semiconductors has introduced a high performance, carrier-grade SPDT switch for Wi-Fi Access Points. The switch has the highest isolation by a factor of 50, it also sets a new bar in linearity, which makes it ideally suited for this fast-growing market. The rising amount of cellular-data offload to Wi-Fi networks is significantly increasing the complexity of access-point radios. Most Wi-Fi access points now contain multiple radios in order to address the capacity demands of cellular data.
The PE42423 is a SPDT Switch that offers 41 dB of port-to-port isolation at 6 GHz. This best-in-class isolation enables multi-radio access points to perform at peak levels without interference between the radios. Exceeding the stringent 802.11ac standard, Peregrine’s switch also offers 65 dBm of linearity to achieve higher data rates. In addition, UltraCMOS technology delivers equally high performance at either 3.3V or 5V, unlike gallium arsenide (GaAs) switches that experience severe performance degradation below 5V. Peregrine’s switch gives networking-product designers the flexibility to operate at lower power supplies and reduce energy consumption.
The PE42423 is now available directly from Peregrine. You can contact Peregrine for evaluation kits, samples, volume-production quantities and pricing.
