Product Specification  
PE4231  
SPDT High Power UltraCMOS™  
Product Description  
DC – 1.3 GHz RF Switch  
The PE4231 SPDT High Power UltraCMOS™ RF Switch is  
designed to cover a broad range of applications from DC to 1.3  
GHz. This single-supply reflective 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 +32 dBm can  
be achieved. The PE4231 also exhibits input-output isolation of  
better than 42 dB at 1.0 GHz and is offered in a small 8-lead  
MSOP package.  
Features  
Optimized for 75 systems  
Single +3-volt power supply  
Low insertion loss: 0.80 dB at 1.0 GHz  
High isolation: 42 dB at 1.0 GHz  
Typical input 1 dB compression point of  
+32 dBm  
Single-pin CMOS or TTL logic control  
Low cost  
The PE4231 SPDT High Power 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.
