The PE426171 is a HaRP?-enhanced All-TX SP12T RF Switch developed on the UltraCMOS? process technology. This MIPI RFFE compliant switch addresses the specific design needs of the 3G/4G Front-End Module Market for use in GSM/EDGE/WCDMA/LTE handsets. The switch incorporates twelve fully symmetric transmit ports that give designers the flexibility to freely configure any combination of ports for any mode and any band through the bi-directional 2-wire serial bus control interface. High isolation and low insertion loss on all paths make this switch ideal for supporting up to 8?UMTS bands and 4 GSM bands with co-banding applied. High ESD tolerance, no blocking capacitor requirements and on-chip SAW filter over-voltage protection give this switch excellent integration and ruggedness. Peregrine’s HaRP? technology enhancements deliver high linearity and excellent harmonics performance with the economy and integration of conventional CMOS. 框图
