The PE426851 is a HaRP?-enhanced all-TX SP8T RF Switch developed on the UltraCMOS? process technology. It addresses the specific design needs of the 3G/4G Front-End Module Market for use in GSM/EDGE/WCDMA/LTE handsets. The switch incorporates eight fully symmetric transmit ports that give designers the flexibility to freely configure any combination of transmit/receive ports for any mode, any band, on any path through a bi-directional 3-wire serial bus control interface. High isolation and low insertion loss on all paths allow this switch to support up to 5 UMTS bands and 4 GSM bands with co-banding applied. On-chip CMOS decode logic facilitates low voltage CMOS control. 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.
