Product Description
The PE42723 is a HaRP™ technology-enhanced reflective SPDT RF switch designed for use in cable applica-
tions including DOCSIS 3.0/1 cable modem, set-top box and residential gateway. It delivers high linearity and
excellent harmonics performance in the 5–1794 MHz band. It also features low insertion loss and high isolation
performance making the PE42723 ideal for DOCSIS 3.1 applications.
The PE42723 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 PE42723 has a maximum 10 kHz switching
frequency. 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 PE42723 spur fundamental occurs around 10
MHz. Its typical performance is –154 dBm/Hz (V1 = H)
and –165 dBm/Hz (V1 = L), with 100 kHz bandwidth.
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

High Frequency Performance with External Matching
High frequency insertion loss and return loss can be improved by inductive matching on the RF ports in the
customer application board layout. Figure 12 is a matching network using a 2.2 nH inductor on each RF port.
The inductor needs to be placed as close to the device under test (DUT) as possible. Figure 13–Figure 15
show the insertion loss and return loss improvement using a 2.2 nH inductor on RFC port and a 2.2 nH on RF1,
RF2 and RFC ports, respectively.
