PE4242 Datasheet, PDF (1/8 Pages) Peregrine Semiconductor Corp. – SPDT UltraCMOS™ RF Switch

Product Description
The PE4242 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from near DC 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 +27 dBm can be achieved.
The PE4242 UltraCMOS™ RF Switch is manufactured in
Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS
process, 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.
