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 1dB compression point of
+33.5 dBm can be achieved.
The PE4259 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.

This pin supports two interface options:
Single-pin control mode. A nominal 3-volt

Complementary-pin control mode. A
complementary CMOS control signal to

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
maximum for extended periods may reduce reliability.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the PE4259 in
the SC70 package is MSL1.
Switching Frequency
The PE4259 has a maximum 25 kHz switching rate.
Note: * All RF pins must be DC blocked with an external series capacitor or
held at 0 VDC.
Note: * To maintain optimum device performance, do not exceed Max PIN at
desired operating frequency (see Figure 4).

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 (VDD). This mode of operation reduces the
number of control lines required and simplifies the
switch control interface typically derived from a
CMOS Processor I/O port.
Complementary-pin control mode allows the
switch to operate using complementary control
pins CTRL and CTRL (pins 4 and 6), that can be
directly driven by +3-volt CMOS logic or a suitable
Processor 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.
Thermal Data
Psi-JT (JT), junction top-of-package, is a thermal
metric to estimate junction temperature of a de-
vice on the customer application PCB (JEDEC
JESD51-2).
JT = (TJ – TT)/P
Where
JT = junction-to-top of package characterization
parameter, °C/W
TJ = die junction temperature, °C
TT = package temperature (top surface, in the
center), °C
P = power dissipated by device, Watts

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
transmission line via the top SMA connector, J1.
RF1 and RF2 are connected through 50
transmission lines via SMA connectors J2 and J3,
respectively. A through 50 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 εr 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 VDD or CTRL input. J7-1 is connected
to the device CTRL input.
