PE42441
UltraCMOS® SP4T RF Switch
10 MHz – 8 GHz
Product Description
The PE42441 is a HaRP™ technology-enhanced
absorptive SP4T RF switch designed for use in various
switching applications spanning multiple markets
including wireless infrastructure, broadband, and wireless
connectivity.
This switch has four symmetric RF ports and delivers low
insertion loss and exceptional isolation. An on-chip
CMOS decode logic facilitates a two-pin low voltage
CMOS control interface. In addition, no external blocking
capacitors are required if 0 VDC is present on RF ports.
The PE42441 is manufactured on Peregrine’s
UltraCMOS® process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate.
Peregrine’s HaRP™ technology enhancements deliver
high linearity and excellent harmonics performance. It is
an innovative feature of the UltraCMOS® process,
offering the performance of GaAs with the economy and
integration of conventional CMOS.

Product Specification
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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS®
devices are immune to latch-up.
Switching Frequency
The PE42441 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.

PRT-28605
Evaluation Kit
The SP4T switch EK Board was designed to ease
customer evaluation of Peregrine’s PE42441. The
RF common port is connected through a 50Ω
transmission line via the top SMA connector, J1.
RF1, RF2, RF3 and RF4 are connected through
50Ω transmission lines via SMA connectors J2, J4,
J3 and J5, respectively. A through 50Ω transmission
is available via SMA connectors J6 and J7. This
transmission line can be used to estimate the loss of
the PCB over the environmental conditions being
evaluated.
The board is constructed of a four metal layer
material with a total thickness of 62 mils. The dual
clad top RF layer is Rogers RO4003 material with
an 8 mil RF core and er = 3.55. The middle layers
provide ground for the transmission lines. The
transmission lines were designed using a coplanar
waveguide with ground plane model using a trace
width of 15 mils, trace gaps of 10 mils, and metal
thickness of 2.1 mils.
