PE4259 Datasheet, PDF (1/9 Pages) Peregrine Semiconductor Corp. – SPDT High Power UltraCMOS™ DC - 3.0 GHz RF Switch
Product Description
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 Ω 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.
