Tue, 11/16/2010 - 7:22am
Peregrine Semiconductor Corporation announced the new PE42662 SP6T (single pole, six throw) RF switch. As the industry's first fully symmetric RF switch, the PE42662 delivers unprecedented design flexibility to manufacturers of 3G front-end modules used in multi-band GSM/EDGE/WCDMA handsets. The switch incorporates six fully symmetric transmit ports that allow designers to freely configure any combination of transmit/receive ports for GSM, EDGE and WCDMA for the first time. The 50-Ohm switch is manufactured on Peregrine's STeP 3 UltraCMOS process and features HaRP technology enhancements to deliver high linearity and exceptional harmonic performance: 2fo/3fo = -40 dBm @ 35 dBm TX (900 MHz) and 33 dBm TX (1900 MHz). The PE42662 switch also features an IIP3 of +68 dBm at 50-Ohm; low transmit insertion loss of 0.5 dB at 900 MHz, 0.6dB at 1900MHz; and very high Isolation of 38dB at 900MHz and 33dB at 1900MHz.
