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.

Absolute Maximum Ratings
Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be
restricted to the limits in Table 2. Operation between operating range maximum and absolute maximum for
extended periods may reduce reliability.
ESD Precautions
When handling this UltraCMOS device, observe the same precautions as with any other ESD-sensitive devices.
Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to
avoid exceeding the rating specified in Table 1.
Latch-up Immunity
Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up.

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

Evaluation Kit
The PE42722 evaluation board was designed to ease customer evaluation of the PE42722 RF switch. The RF
common port is connected through a 75Ω transmission line via the F-Type connector, J1. RF1 and RF2 ports are
connected through 75Ω transmission lines via F-Type connectors J2 and J3, respectively. A 75Ω through trans-
mission line is available via F-Type connectors J5 (THRU left) and J6 (THRU right), which can be used to de-
embed the loss of the PCB. DC power is supplied through J10, with VDD on pin 9, and GND on the entire lower
row of even numbered pins. To evaluate a switch path, add or remove jumpers on V1 (pin 3) using Table 5.
Series 6.2 nH inductors are used on the three RF ports to provide impedance matching.
