The PE 42 37 RF Swit c h is des ign ed to c ov er a bro ad r an ge of

applications from near DC to 4000 MHz. This reflective switch

integrates on-board CMOS contro l logic driven by a single-pin,

low voltage CMOS or TTL control input. Using a nominal +3-

volt power supply, a 1 dB compression point of +32 dBm can

be achieved. The PE4237 also exhibits outstanding isolation

of better than 43 dB at 1000 MHz and is

offe red in a small 3x3 mm DFN package.

The PE4237 is manufactured on Peregrine’s UltraCMOS™

pro c ess, a patented variation of silicon-on-in sulator (SO I)

technology on a sapphire substrate, offering the performance

of GaAs with the econom y an d i nte gr ation of conventi on al

CMOS.

Electrostatic Discharge (ESD) Precautions

When hand ling this UltraCMOS ™ devi ce, obs erve

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 4.

Latc h-Up Avoidance

Unlike conventional CMO S device s, UltraCMOS™

devices are immune to latch-up.

Table 3. Operating Ranges

Notes: 1. All RF pins must be DC blocked with an external series

capacitor or held at 0 VDC.

Control Logic Input

The control logic input pin (CTRL) is typically

driven by a 3-volt CMOS logic level signal. For

flexibility to support systems that have 5-volt

control logic drivers, the control logic input has

been designed to handle a standard 5-volt TTL

control signal. This TTL control signal input must

not exceed 5-volts or damage to the switch could

result.

Moist u re Sen sit i vit y L evel

The Moisture Sensitivity Level rating for the

PE4237 in the 6-lead 3x3 DFN package is MSL1.

Evaluation Kit

The SPDT Switch Evaluation Kit board was

designed to ease customer evaluation of the

PE4237 SPDT switch. The RF common port is

connected through a 50 Ω transmission line to the

top left SMA connector, J1. Port 1 and Port 2 are

connected through 50 Ω transmission lines to the top

two SMA connectors on the right side of the board,

J2 and J3. A through transmission line connects

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 provides a means for controlling DC and digital

inputs to the device. Starting from the lower left pin,

the second pin to the right (J6-3) is connected to the

device CNTL input. The fourth pin to the right (J6-7)

is connected to the device VDD input. A decoupling

capacitor (100 pF) is provided on both CTRL and

VDD trace s . It is the re s pons ibility 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.
