The PE4273 RF Switch is designed for the TV tuner, PCTV, set

top box, DTV, DVR and general broadband applications. This

device offers industry leading broadband linearity, 1.5 kV ESD

tolerance and a simple CMOS interface. It offers a simple

alternative solution to pin diode and mechanical relay switches.

The PE4273 SPDT B roadband RF Switch is manufac tured on

Peregrine’s UltraCMOS™ process, a patented variation of

silicon -on-insulator (SOI ) technology on a sapphire sub s t rate,

off eri ng th e per formance of GaAs wit h th e eco no m y and

integration of conventional CMOS.

Electrostatic Discharge (ESD) Precautions

When hand ling this UltraCMOS ™ devi ce, 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.

Latc h-Up Avoidance

Unlike conventional CMO S device s, UltraCMOS™

devices are immune to latch-up.

Control Logic Input

The PE4273 is a versatile RF CMOS switch that

supports two operating control modes; single-pin

control mode and complementary-pin control

mode.

Single-pi n control m od e enables the swit ch to

operate with a single control pin (pin 4) supporting

a +3 -volt CMOS logic input, and requires a

dedicated +3-volt powe r supply connection (pin 6).

Thi s mo de of op er ation red uc e s the number of

control lines required and simp lifies 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 ( pi ns 4 & 6), that c a n be di r ectl y

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 oper ating li m i ts.

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 r 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.
