The PE42422 is a HaRP-enhanced SPDT RF switch designed to cover a broad range of applications from 5 MHz to 6 GHz. This reflective switch integrates on-board CMOS control logic with a low voltage CMOS-compatible control interface requiring no external components. Typical insertion loss figures range from 0.23 dB at 100 MHz to 0.9 dB at 9 GHz. Peregrines HaRP technology ensures high linearity and excellent harmonics performance. The chip has high ESD tolerance of 4 kV Human Body Model on the RF pins to ground and 1 kV on all other pins.

Key features of the PE42422:
