Product Description
The PE42542 is a HaRP™ technology-enhanced
absorptive SP4T RF switch designed for use in Test/
ATE, microwave and other wireless applications. This
broadband general purpose switch maintains excellent
RF performance and linearity from 9 kHz through
18 GHz. The PE42542 exhibits low insertion loss,
high isolation performance and has fast settling time.
No blocking capacitors are required if DC voltage is
not present on the RF ports.
The PE42542 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
Evaluation Kit
The SP4T switch evaluation board was designed
to ease customer evaluation of Peregrine’s
PE42542. The RF common port is connected
through a 50Ω transmission line via the SMA
connector, J1. RF1, RF2, RF3 and RF4 ports are
connected through 50Ω transmission lines via
SMA connectors J4, J3, J2 and J5, respectively.
A 50Ω through transmission line is available via
SMA connectors J6 and J7, which can be used to
de-embed the loss of the PCB. J13 provides DC
and digital inputs to the device.
The board is constructed of a four metal layer
material with a total thickness of 62 mils. The top
RF layer is Rogers 4360 material with a thickness
of 32 mils and the r = 6.4. 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 18 mils, trace gaps of 7 mils
and metal thickness of 2.1 mils.
For the true performance of the PE42542 to be
realized, the PCB should be designed in such a
way that RF transmission lines and sensitive DC
I/O traces are heavily isolated from one another.
High frequency insertion loss and return loss can
be further improved by external series inductive
tuning traces in the customer application board
layout. For example, to improve 12–18 GHz
performance, use ~180 pH for RFX ports and
~50 pH for RFC port.
Vector de-embed is recommended to more
accurately calculate the performance of the
DUT. Refer to Application Note 39 “Vector De-
embedding of the PE42542 and PE42543 SP4T
RF Switches” for additional information. The half
thru line data file can be downloaded from
Peregrine’s website to facilitate the vector de-
embedding.
