Features
Product Description
•
•
Single +3.0-volt Power Supply
The PE4244 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from DC to 3.0 GHz. This switch
integrates on-board CMOS control logic with a low voltage
CMOS compatible control input. Using a +3-volt nominal power
supply voltage, a 1 dB compression point of +27 dBm can be
achieved. The PE4244 also exhibits excellent isolation of 39 dB
at 1.0 GHz and is offered in a small 8-lead MSOP package.
Low Insertion loss: 0.60 dB up to
2.0 GHz
•
High isolation of 39 dB at 1.0 GHz,
29 dB at 2.0 GHz

•
Typical 1 dB compression of +27 dBm
Single-pin CMOS logic control
Packaged in 8-lead MSOP
The PE4244 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.
RF1 port (Note 1)
Note 1: All RF pins must be DC blocked with an external
series capacitor or held at 0 VDC
.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.

Peregrine specification 101/0037
Evaluation Kit
The SPDT Switch Evaluation Kit board was
designed to ease customer evaluation of the
PE4244 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 J4. A through transmission line connects
SMA connectors J6 and J8. 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 0.030”, trace gaps of 0.007”,
dielectric thickness of 0.028”, metal thickness of
0.0014” and εr of 4.4.
J2 provides a means for controlling DC and digital
inputs to the device. Starting from the lower left pin,
the second pin to the right (J2-3) is connected to the
device CTRL input. The fourth pin to the right (J2-7)
is connected to the device VDD input. A decoupling
capacitor (100 pF) is provided on both CTRL and
V
DD traces. It is the responsibility of the customer to
determine proper supply decoupling for their design
application. Removing these components from the
evaluation board has not been shown to degrade RF
performance.
