The PE4271 is a is a high-isolation Switch designed for CATV

applications, covering a broad frequency range from near DC

up to 3000 MHz. This single-supply SPST switch offers a

single-pin CMOS control inte rface with industry leading CTB

performance. It also provides low insertion loss, high isolation

and extremely low bias requirements while operating on a

single 3-volt supply. In a typical CATV application, the PE4271

provides for a cost effective and manufacturable solution vs.

mechanical relays.

The PE4271 is manufactured on Peregrine’s UltraCMOS™

pro cess, a patented variation of silicon-on-insulator (SOI)

technology on a sapphire substrate, offering the performance

of GaAs with the econom y an d i nte gr ation 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 rating specified in Table 3.

Latc h-Up Avoidance

Unlike conven tional CMOS devices , UltraCMOS™

devices are immune to latch-up.

Device Description

The PE4271 high isolation SPST CATV Switch is

designed to support CATV applications such as

premium channel service connect/disconnect switch

blocks. This function is typica lly performed by bulky

and expensive mechanical switches. The high

isolation characteristics (60 dB at 1 GHz, 85 dB at

5 MHz), high compression point, and an integrated

75  (0.25 watt) input termination make the PE4271

an ideal, low cos t so lution.

The control logic input pin (CTRL) is typically driven

by a 3-volt CMOS logic level signal, and has a

threshold of 50% of VDD. For flexibility to s up po rt

systems th at have 5-volt con t rol logic drivers, the

control logic input has been designed to handle a 5-

volt logic HIGH signal. (A minimal current will be

sourced out of the VDD pin when the control logic

input voltage level exceeds VDD.)

Notes: 1. CTRL accepts both CMOS and TTL voltage leads.

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.

Evaluation Kit

The PE4271 EK board was designed to ease

customer eval u ati o n of Per e gr i n e’ s hi gh

performance SPST CATV MOSFET switch. RF1

is connected through a 75  transmission line via

the top left F connector, J1. RF2 is connected

through a 75  transm iss ion line via the top right

F c onnec tor, J2. A 75  through tr ansmissi on line

is available via F connectors J3 and J4. This

transmission line can be used to estimate the loss

of the PCB over the environmental conditions

bein g ev aluated . VDD is supplied via J6 -2, while

the contro l logic voltage is supplied via J5-2. It is

the re sponsib ility of the customer to determine

proper supply decoupling for their design

application. It has been observed that by

removing C1 and C2 from the evaluation board

has not shown to degrade RF performance.

The board is constructed of a two me tal 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 model with

trace width of 0.021”, trace gaps of 0.030”,

dielectric thickness of 0.028”, metal thickness of

0.0021 ” and r of 4.6. Note that the predominate

mode for these transmission lines is coplanar

waveguide with a ground plane.
