Product Specification
PE4241
SPDT UltraCMOS™ RF Switch
Features
Product Description
• Single-pin or complementary CMOS
The PE4241 UltraCMOS™ RF Switch is designed to cover a
broad range of applications from DC through 3.0 GHz. 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.
logic control inputs
• +3.0-volt power supply needed for
single-pin control mode
• Low insertion loss: 0.7 dB at 1.0 GHz,
0.9 dB at 2.0 GHz
• Isolation of 30 dB at 1.0 GHz, 21 dB at
2.0 GHz
The PE4241 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.
• Typical input 1 dB compression point of
+27 dBm
• Ultra-small SOT23 package

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.
