Peregrine Semiconductor unveils antenna tuning switch


Peregrine Semiconductor, a supplier of high-performance RF CMOS and mixed-signal communications ICs, today unveiled the UltraCMOS PE42641 SP4T antenna tuning switch delivering an unparalleled IMD performance of -110 dBm, making it ideal for converged designs requiring high linearity and low distortion.

A variety of emerging market applications benefit from the exceptional RF performance advantages of the PE42641 switch, including 3G GSM/EDGE/WCDMA and CDMA handset and PC card applications; machine-to-machine applications such as vending machines and parking meters; or designs requiring antenna tuning, such as repeater and telematics applications.

The UltraCMOS silicon-on-sapphire based PE42641 incorporates Peregrine's revolutionary HaRP technology enhancements to deliver exceptional harmonic results, linearity and overall RF performance: high linearity of +68 dBm IP3 or -110 dBm IMD; harmonics better than -80 dBc, low insertion loss of 0.5 dB (typ); high isolation 35 dB at critical paths; and complete monolithic integration.

Additionally, the new switch offers Class 2 ESD (2 kV HBM) on all pins, and Class 3 (4 kV HBM) at the antenna, which is the highest ANT-pin ESD protection available today.

With the UltraCMOS PE42641, the industry is finally able to deliver on the promise of tuning capability in mobile devices, a challenge which has been on the whiteboards of antenna designers for many years.  The PE42641 is Peregrine's first step in supporting the emerging market of tunable

Further, as with the entire Peregrine portfolio, this SP4T is developed on UltraCMOS which is a standard CMOS technology. It leverages all the same low-cost, high-value benefits in manufacturing yields, scalability and ease-of-use, while delivering the unprecedented performance offered only with our proprietary sapphire substrate.   For high-performance switch applications at any throw-count, UltraCMOS is the future.
