Product Specification
PE42641
Product Description
The PE42641 is a HaRP™-enhanced SP4T RF switch
developed on the UltraCMOS
®
process technology. This
switch contains 4 identical WEDGE/CDMA compliant TX
paths and can be used in various GSM and WCDMA
mobile applications as well as other wireless applications
up to 3000 MHz. It is also suitable for antenna band
switching and switchable matching networks for cellular
and non-cellular mobile applications. It integrates on-
board CMOS control logic with a low voltage CMOS-
compatible control interface and requires no DC blocking
capacitors. This RoHS-compliant part is available in a
standard 3

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.

PE42641
Product Specification
Evaluation Kit
The SP4T switch EK Board was designed to
ease customer evaluation of Peregrine’s
PE42641. The RF common port is connected
through a 50
Ω
transmission line via the top SMA
connector, J1. RF1, RF2, RF3 and RF4 are
connected through 50
Ω
transmission lines via
SMA connectors J3, J5, J2 and J4, respectively.
A through 50
Ω
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
FR4 material with a total thickness of 62 mils.
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
32 mils, trace gaps of 25 mils, and metal
thickness of 2.1 mils.
