Dubbed PE42440, the HaRP-enhanced switch's linearity performance makes it well-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 PE42440 features an IIP3 of +67 dBm and P1dB of 41.5 dBm (across the range); insertion loss of 0.45 dB; and high isolation of 34 dB (at 1 GHz). The 50-Ohm switch handles maximum+33 dBm input power (500 MHz to 3 GHz) with ESD tolerance of 4.0 kV HBM on the RFC pin.

Additional features include integrated CMOS control logic, decoder for 2-pin control that accepts 1.8V and 2.75V control logic levels, and a low 4.5 Ohm series ON resistance. A single Vdd supply pin eliminates the need for multiple power supplies and power up sequencing. The device settles fast without gate lag or insertion loss drift, and no blocking capacitors are required.

The PE42440 is packaged in a 16-lead 3mmx3mm QFN.
