Product Description
The PE42722 is a HaRP™ technology-enhanced reflective SPDT RF switch designed for use in cable applica-
tions including DOCSIS 3.0/1 cable modem and set-top box. It delivers high linearity and excellent harmonics
performance in the 5–1794 MHz band. It also features low insertion loss and high isolation performance that
makes the PE42722 ideal for DOCSIS 3.1 applications.
The PE42722 is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator
(SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of
conventional CMOS.

SPDT RF Switch
Switching Frequency
The PE42722 has a maximum 25 kHz switching rate.
Switching frequency describes the time duration
between switching events. Switching time is the time
duration between the point the control signal reached
50% of the final value and the point the output signal
reaches within 10% or 90% of its target value.
Spurious Performance
The typical spurious performance of the PE42722 is
–137 dBm.
Thermal Data
Psi-JT (JT), junction top-of-package, is a thermal
metric to estimate junction temperature of a device on
the customer application PCB (JEDEC JESD51-2).
JT = (TJ – TT)/P
where
JT = junction-to-top of package characterization
parameter, °C/W
TJ = die junction temperature, °C
TT = package temperature (top surface, in the
center), °C
P = power dissipated by device, Watts
