The PE4239 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from DC through 3.0 GHz. 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 +27 dBm can be achieved.
The PE4239 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.

Control Logic Input
The PE4239 is a very versatile RF CMOS switch
that supp or ts tw o op er ating co ntr ol m od es ; si ngl e-
pin control mode and complementary-pin control
mode.
Single-pi n co ntr ol m od e 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 simpli fies 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 PE4239 to
be used as a potential alternate source for SPDT
RF switch products used in positive control
voltage mode and operating within the PE4239
operating limits.

Evaluation Kit
The SPDT Switch Evaluation Kit board was
designed to ease c ustomer ev al u ation of the
PE42 39 SP DT swit ch. The RF common port is
connected through a 50 transmis si on line to th e
top left SMA connector, J1. Port 1 and Port 2 are
conne cted thr ough 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
envir o nm e ntal c o ndi tions bei ng evalua te d.
The board is constructed of a two metal laye r 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 provide s a means for contro lling DC and dig ita l
inputs to the device. Starting from the lower le ft
pin, the second pin to the right (J6-3) is connected
to the de vice V1 or CTRL input. The fourth pin to
the right (J6-7) is connected to the device V2 or
CTRL/VDD input.
