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 SPDT High Power RF Switch 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.

Notes: 1. Device linearity will begin to degrade below 10 MHz.

2. The DC transient at the output of any port of the switch when the control voltage is switched from Low to High or High to Low in a 50

test

set-up, measured with 1ns risetime pulses and 500 MHz bandwidth.

3. A tuning capacitor must be added to the application board to optimize the insertion loss and return loss performance. See Figure 6 for

details.
