The PE4259 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from 10 MHz through 3000 MHz.
This reflective switch integrates on-board CMOS control logic
with a low voltage CMOS-compatible control interface, and can
be controlled using either single-pin or complementary control
inputs. Using a nominal +3-volt power supply voltage, a typical
input 1 dB compression point of +33.5 dBm can be achieved.
The PE4259 SPDT High Power RF Switch is manufactured on
Peregrine’s UltraCMOS™ process, a patented variation of
silicon-on-insulator (SOI) technology on a sapphire substrate,
offering the performance of GaAs with the economy and
integration of conventional CMOS.

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.

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 absolute

The Moisture Sensitivity Level rating for the PE4259 in
the SC70 package is MSL1.

Control Logic Input
The PE4259 is a versatile RF CMOS switch that
supports two operating control modes; single-pin
control mode and complementary-pin control
mode.
Single-pin control mode enables the switch to
operate with a single control pin (pin 4) supporting
a +3-volt CMOS logic input, and requires a
dedicated +3-volt power supply connection on pin
6 (V
DD
). This mode of operation reduces the
number of control lines required and simplifies the
switch control interface typically derived from a
CMOS µProcessor I/O port.
Complementary-pin control mode allows the
switch to operate using complementary control
pins CTRL and CTRL (pins 4 & 6), that can be
directly driven by +3-volt CMOS logic or a suitable
µProcessor I/O port. This enables the PE4259 to
be used as a potential alternate source for SPDT
RF switch products used in positive control
voltage mode and operating within the PE4259
operating limits.

Evaluation Kit
The SPDT switch EK Board was designed to ease
customer evaluation of Peregrine’s PE4259. The
RF common port is connected through a 50 Ω
transmission line via the top SMA connector, J1.
RF1 and RF2 are connected through 50 Ω
transmission lines via SMA connectors J2 and J3,
respectively. A through 50 Ω transmission is
available via SMA connectors J4 and J5. 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 two metal layer FR4
material with a total thickness of 0.031”. The
bottom layer provides ground for the RF
transmission lines. The transmission lines were
designed using a coplanar waveguide with ground
plane model using a trace width of 0.0476”, trace
gaps of 0.030”, dielectric thickness of 0.028”,
metal thickness of 0.0021” and ε
r
of 4.4.
J6 and J7 provide a means for controlling DC and
digital inputs to the device. J6-1 is connected to
the device V
DD
or CTRL input. J7-1 is connected
to the device CTRL input.
