Peregrine Semiconductor Corporation announces the new PE42440 SP4T (single pole four throw) RF switch. The PE42440, designed on Peregrine's green UltraCMOS™ silicon-on-sapphire (SOS) process technology, features excellent broadband RF performance from 50 MHz up to 3 GHz. The HaRP™ — enhanced switch has best-in-class linearity, making it suited for general purpose TRx switching in cellular and 2.4 GHz industrial; scientific and medical (ISM) radio bands; antenna tuning; and filter bank tuning/switching in a wide range of applications, including cellular radios and radio modules; antenna tuning of UHF bands through 3 GHz; RFID antenna tuning; 2.4 GHz ISM; Femtocells and other industrial applications. The new reflective PE42440 switch delivers impressive performance, an IIP3 of +67 dBm and P1dB of 41.5 dBm (across the range); Insertion Loss of 0.45 dB; and very high Isolation of 34 dB (at 1 GHz). The 50-Ohm switch handles maximum +33 dBm input power (500 MHz to 3 GHz) with world-class ESD tolerance of 4.0 kV HBM on the RFC pin.
