Peregrine Semiconductor’s new PE42430 is a single-pole triple-throw (SP3T) RF switch developed on patented UltraCMOS technology. It combines low insertion loss with high linearity, high isolation and small package size, making it well suited for WLAN and Bluetooth applications in the 2,4 GHz band, as well as general broadband switching applications.
An on-chip CMOS decode logic facilitates a three-pin CMOS control interface and, because VDD is derived from switch-control inputs, there is no need for a VDD pin.
Peregrine’s HaRP technology enhancements enable IIP3 linearity of 66 dBm. This combines with low insertion loss of 0,45 dB @ 1 GHz and 0,55 dB @ 2,5 GHz, and high isolation of 40 dB @ 1 GHz and 30 dB @ 2,5 GHz.
The device provides ESD tolerance of 4500 V HBM and 250 V MM on all ports, and is available in an 8-lead, 1,5 x 1,5 mm DFN package.
