Product Specification
PE4283
Product Description
The PE4283 RF Switch is designed to cover a broad range
of applications from DC through 4000 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. The PE4283 operates using a +3 volt power supply.
The PE4283 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.

Description
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
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 rating specified in Table 3.
Switch control input, CMOS logic level.
RF Common

This pin supports two interface options:
Single-pin control mode.
A nominal 3-volt
supply connection is required.
Complementary-pin control mode.
A
complementary CMOS control signal
to V1 is supplied to this pin.

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.

Control Logic Input
The PE4283 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 (pin 6).
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 V1 and V2 (pins 4 & 6), that can be directly
driven by +3-volt CMOS logic or a suitable
µProcessor
I/O port. This enables the PE4283 to
operate in positive control voltage mode within the
PE4283 operating limits.

Product Specification
Evaluation Kit
The SPDT switch EK Board was designed to ease
customer evaluation of Peregrine’s PE4283. The
RF common (RFC) 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 V2 input. J7-1 is connected to the
device V1 input. Series resistors (R1 and R2) are
provided to reduce the package resonance
between RF and DC lines.
