Multi-throw Count RF Switch EVK User’s Manual Introduction Introduction The SP6T (PE42562, PE42462, PE426462), SP8T (PE42582, PE42482, PE426482) and SP12T (PE42512, PE42412, PE426412) are HaRP™ technology-enhanced absorptive high throw count RF switches manufac- ® tured on Peregrine’s UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology. These products deliver high port-to-port isolation, low insertion loss and fast switching time, making them ideal for filter bank switching and RF signal routing in test and measurement (T&M) and wireless applications up to 8 GHz.
Multi-throw Count RF Switch EVK User’s Manual Evaluation Board Assembly SP6T Evaluation Board Assembly Overview The SP6T evaluation board (EVB) is assembled with the PE42562, PE42462 or PE426462, test headers and SMA connectors. The RF traces from each SMA connector to the RF switch are equal length, easing the task of de-embedding.
