Product Description
The PE42721 is a HaRP™ technology-enhanced
absorptive 75Ω SPDT RF switch developed on the
UltraCMOS® process technology.
PE42721 is a highly linear device delivering high
isolation and very low insertion loss performance. It is
designed for broadband applications such as TV
tuner modules, CATV signal switching and
distribution, DTV, multi-tuner digital video recorders
(DVRs) and set-top boxes.
PE42721 supports +1.8V control logic and offers high
ESD protection. PE42721 is pin compatible to
PE42750. In addition, no blocking capacitors are
required if DC voltage is not present on the RF ports.
Peregrine’s HaRP™ technology enhancement is an
innovative feature of the UltraCMOS® process,
offering the performance of GaAs with the economy
and integration of conventional CMOS.

blocking capacitors for proper operation if the 0V DC requirement is
met
Exceeding absolute maximum ratings may cause
permanent damage. Operation should be restricted
to the limits in the Operating Ranges table.
Operation between operating range maximum and

Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS®
devices are immune to latch-up.
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS® device, observe
the same precautions that you would use with
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 specified rating.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE42721 in the 12-lead 3x3 mm QFN package is
MSL1.

Switching Frequency
The PE42721 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
reaches 50% of the final value and the point the
output signal reaches within 10% or 90% of its
target value. Switching time is provided in Table 1.
Spurious Performance
The typical spurious performance of the PE42721
is –124 dBm.

Evaluation Board Figure 19. Evaluation Board Layout
The SPDT switch evaluation board was designed
to ease customer evaluation of Peregrine’s
PE42721. The RF common port is connected
through a 75Ω transmission line via the F-Type
connector, J2. RF1 and RF2 ports are connected
through 75Ω transmission lines via F-Type
connectors J1 and J3, respectively. A 75Ω through
transmission line is available via F-Type
connectors J4 and J5, which can be used to
de-embed the loss of the PCB. J6 provides DC and
digital inputs to the device.
