Highly linear antenna tuning switch

29 April 2009 Telecoms, Datacoms, Wireless, IoT

Peregrine Semiconductor recently released the UltraCMOS PE42641 SP4T antenna tuning switch, delivering IMD performance of -110 dBm, making it well suited to converged designs requiring high linearity and low distortion. A variety of emerging market applications can benefit from the RF performance of the switch, including 3G GSM/EDGE/WCDMA and CDMA handset and PC card applications, machine-to-machine applications such as vending machines and parking meters, and designs requiring antenna tuning, such as repeater and telematics applications.

The PE42641 incorporates Peregrine’s 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; high isolation of 35 dB at critical paths; and complete monolithic integration. Additionally, the switch offers Class 2 ESD (2 kV HBM) on all pins, and Class 3 (4 kV HBM) at the antenna.

The 50 Ω, 2,75 V PE42641 operates from 100 to 3000 MHz and provides additional features such as onboard CMOS logic which facilitates 1,8 V or 2,75 V control, 4,5Ω series ON resistance, no blocking capacitors and fast switch settling time. The device is available in a RoHS-compliant 3 x 3 x 0,75 mm TQFN package.
