4270-00 - PEREGRINE SEMICONDUCTOR

Page 1 of 8

The PE4270 is a is a high-isolation Switch designed for CATV

applications, covering a broad frequency range from 1 to 3000

MHz. This single-supply SPST switch offers a single-pin

CMOS control interface 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 PE4270

provides for a cost effective and manufacturable solution vs.

mechanical relays.

The PE4270 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.

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.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS™

devices are immune to latch-up.

Table 4. Operating Ranges

Notes: 1. Both RF pins must be held at 0 VDC or require external DC

blocking capacitors

2. The exposed pad must be soldered to the ground plane for

proper switch performance.

Device Description

The PE4270 high isolation SPST CATV Switch is

designed to support CATV applications such as

premise disconnect of a CATV signal path. This

function is typically performed by bulky and

expensive mechanical relays. The high isolation

characteristics, high compression point, and

integrated 75-ohm terminations make the PE4270

an ideal, cost effective and manufacturable

product of choice.

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

support systems that have 5-volt control 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 PE4270 EK board was designed to ease

customer evaluation of Peregrine’s high

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  transmission line via the top right

F connector, J2. A 75  through transmission 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

being evaluated. VDD is supplied via J6-2, while

the control logic voltage is supplied via J5-2. It is

the responsibility 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 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 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.
