Product Specification  
PE4220  
SPDT UltraCMOS™ RF Switch  
DC - 2500 MHz  
Product Description  
Features  
The PE4220 UltraCMOS™ RF Switch is designed to cover a  
broad range of applications from near DC to 2500 MHz. This  
single-supply switch integrates on-board CMOS control logic  
driven by a simple, single-pin CMOS or TTL compatible control  
input. Using a nominal +3-volt power supply, a typical input 1  
dB compression point of +22 dBm can be achieved. The  
PE4220 also exhibits input-output isolation of better than 37 dB  
at 1000 MHz and is offered in a small 8-lead MSOP package.  
Single 3-volt power supply  
Very low insertion loss: 0.25 dB at  
1000 MHz  
High isolation: 37 dB at 1.0 GHz  
Typical input 1 dB compression point  
of +22.5 dBm  
Single-pin CMOS or TTL logic control  
Packaged in a small 8-lead MSOP  
The PE4220 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.
