The PE4259 UltraCMOS™ RF switch is designed to

cover a broad range of applications from 10 MHz

through 3000 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. Using a nominal +3-volt power supply

voltage, a typical input 1 dB compression point of

+33.5 dBm can be achieved.

The PE4259 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

specified rating.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS™

devices are immune to latch-up.

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.

Moisture Sensitivity Level

The Moisture Sensitivity Level rating for the PE4259 in

the SC70 package is MSL1.

Switching Frequency

The PE4259 has a maximum 25 kHz switching rate.

Note 1: All RF pins must be DC blocked with an external series capacitor or

held at o VDC

Note 1: To maintain optimum device performance, do not exceed Max PIN at

desired operating frequency (see Figure 4).

Control Logic Input

The PE4259 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 on

pin 6 (VDD). This mode of operation reduces the

number of control lines required and simplifies the

switch control interface typically derived from a

CMOS Processor I/O port.

Complementary-pin control mode allows the

switch to operate using complementary control

pins CTRL and CTRL (pins 4 and 6), that can be

directly driven by +3-volt CMOS logic or a suitable

Processor I/O port. This enables the PE4259 to

be used as a potential alternate source for SPDT

RF switch products used in positive control

voltage mode and operating within the PE4259

operating limits.

Evaluation Kit

The SPDT switch EK Board was designed to ease

customer evaluation of Peregrine’s PE4259. The

RF common 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 εr 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 VDD or CTRL input. J7-1 is connected

to the device CTRL input.
