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

Note: 5. Operating within DC limits (Table 4).
Absolute Maximum Ratings are those values

may cause permanent device damage.
Functional operation should be restricted to the
limits in the DC Electrical Specifications table.
Exposure to absolute maximum ratings for
extended periods may affect device reliability.

Product Specification
Table 5. Single-pin Control Logic Truth Table
Control Logic Input
Control Voltages
Signal Path
The PE4273 is a versatile RF CMOS switch that
supports two operating control modes; single-pin
control mode and complementary-pin control
mode.
Pin 6 (V2) = VDD
Pin 4 (V1) = High
RFC to RF1
Pin 6 (V2) = VDD
Pin 4 (V1) = Low
RFC to RF2
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.
Table 6. Complementary-pin Control Logic
Truth Table
Control Voltages
Signal Path
Pin 6 (V2) = Low
Pin 4 (V1) = High
RFC to RF1
Pin 6 (V2) = High
Pin 4 (V1) = Low
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 PE4273 to
operate in positive control voltage mode within the
PE4273 operating limits.

Peregrine Specification 101/0245
Evaluation Kit
The SPDT Switch Evaluation Kit board was
designed to ease customer evaluation of the
PE4273 SPDT switch. The RF common port is
connected through a 75 ꢀ transmission line to the
bottom F connector, J2. Port 1 and Port 2 are
connected through 75 ꢀ transmission lines to two F
connectors on either side of the board, J3 and J1. A
through transmission line connects F 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 0.021”, trace gaps of 0.030”,
dielectric thickness of 0.028”, copper thickness of
0.0021” and εr of 4.3.
J6 and J7 provide a means for controlling the DC
inputs to the device. The lower left header (J6) is
connected to the device V1 input. The lower right
header (J7) is connected to the device V2 input.
Series resistors (R1 and R2) are provided to reduce
the package resonance between RF and DC lines.
Footprints for decoupling capacitors (100 pF) are
provided on both V1 and V2 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.
