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, of fering the perf ormance of GaAs with th e economy and integration of
conventional CMOS.

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 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.

Evaluation Kit
The PE42723 evaluation board was designed to ease customer evaluation of the PE42723 RF switch. The RF
common port is connected through a 75 Ω transmission line via the F-Type connector, J3. RF1 and RF2 ports are
connected through 75Ω transmission lines via F-Type connectors J1 and J2, respectively. A 75Ω through trans-
mission line is available via F-Type connectors J4 (THRU left) and J5 (THRU right), which can be used to de-
embed the loss of the PCB. J6 provides DC and digital inputs to the device.
