The PE42440 is a HaRP™-enhanced SP4T RF Switch
developed on the UltraCMOS™ process technology. This
general-purpose switch contains 4 identical RF ports and can
be used in a multitude of applications up to 3000 MHz. 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 3x3x0.75mm QFN package.
Peregrine’s HaRP™ technology enhancements deliver high
li near it y an d ex ce pti o nal har m oni cs p er for m a nc e. It is an
innovative feature of the UltraCMOS™ process, providing
performance superior to GaAs with the economy and
integration of conventional CMOS.

Electrostatic Discharge (ESD) Precautions
When handling t his Ultr aCM OS™ device, obs er v e the

circ uitry to protect it from dam age due to ES D,
precautions should be taken t o av oid ex c eeding the

Evaluation Kit
The SP4T switch EK Board was designed to ease
customer evaluation of Peregrine’s PE42440. The
RF common port is connected through a 50
transmission line via the top SMA connector, J1.
RF1, RF2, RF3 and RF4 are connected through
50 transmission lines via SMA connectors J3,
J5, J2 and J4, respectively. A through 50
transmission is available via SMA connectors J6
and J7. This transmission line can be used to
estimate the loss of the PCB over the
envir o nm e ntal c o ndi tions bei ng ev al ua ted.
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.
