SP6T all-Tx RF switch delivers fully symmetric flexibility
September 15, 2010 // Jean-Pierre Joosting
Peregrine Semiconductor has announced the PE42662 SP6T (single pole, six throw) RF switch, which claims to be the industry's first fully symmetric RF switch and delivers a high level of 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 PE42662 is the latest release in Peregrine’s UltraCMOS™ silicon-on-sapphire (SOS) mobile wireless switch portfolio targeted at the high-volume cellular handset market.
The 50-Ohm switch is manufactured on the company’s STeP 3 UltraCMOS process and features HaRP™ technology enhancements to deliver high linearity and exceptional harmonic performance: 2fo/3fo = -40 dBm at 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. The switch handles maximum +35 dBm input power with world-class ESD tolerance of 4000V HBM at ANT port, and 2000V HBM on all ports.
The combination of performance and design flexibility of the PE42662 raises the bar for RF switches. RF front-end module designers can now develop cleaner layouts with a common universal die, reduce time and cost in the development process, and still address the multiple variations required to support different modules and 3G handsets without compromising increased feature integration, ruggedness and high performance.
Additional features of the PE42662 switch include an on-chip CMOS decode logic that facilitates three-pin low voltage CMOS control and low-power standby state, as well as on-chip SAW filter over-voltage protection devices. As with all SOS-based UltraCMOS RFICs, no blocking capacitors are required.
The PE42662 is available in the highly efficient flip-chip die form in volume today.
