The PE4242 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from near DC through 3000 MHz.
This reflective switch integrates on-board CMOS control logic
with a low voltage CMOS-compatible control int erface, 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 +27 dBm can be achieved.
The PE4242 UltraCMOS™ RF Switch is manufactured in
Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS
process, 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, UltraCMO S™
devices are immune to latch-up.

Control Logic Input
The PE4242 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 µPr ocessor 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 PE4242 to
be used as a potential alternate source for SPDT
RF switch products used in positive control
voltage mode and operating within the PE4242
operating limits.

Evaluation Kit
The SPDT Switch Evaluation Kit board was
designed to ease customer evaluation of the
PE4242 SPDT switch. The RF common port is
connected through a 50 transmission line to the
top left SMA connector, J1. Port 1 and Port 2 are
connected through 50 transmission lines to the
top two SMA connectors on the right side of the
board, J3 and J2, respectively. A through
transmission line connects 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 r of 4.4.
J6 provides a means for controlling DC and digital
inputs to the device. Starting from the lower left
pin, the second pin to the right (J6-3) is connected
to the device V1 or CTRL input. The fourth pin to
the right (J6-7) is connected to the device V2 or
CTRL/VDD input.
