Peregrine Semiconductor claims its latest antenna tuning switch supports IMD performance of -110dBm, making it suitable for converged designs requiring high linearity and low distortion.

Namely, this is 3G GSM/EDGE/WCDMA and CDMA handset and PC card applications.

The silicon-on-sapphire based PE42641 device has a linearity of +68dBm IP3 or -110dBm IMD; harmonics better than -80dBc, low insertion loss of 0.5dB (typ); high isolation 35dB at critical paths; and complete monolithic integration.

The switch also offers Class 2 ESD (2 kV HBM) on all pins, and Class 3 (4 kV HBM) at the antenna.

The 50ohm RF switch operates from 100-3000MHz and provides many additional features, including on-board CMOS logic which facilitates 1.8V or 2.75V control; 4.5ohm series ON resistance; no blocking capacitors; and fast switch settling time.

The device is available in a RoHS-compliant 3x3x0.75mm TQFN package.
