Product Specification  
PE4239  
SPDT UltraCMOS™ RF Switch  
Features  
Product Description  
• Single-pin or complementary CMOS  
The PE4239 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 32 dB at 1.0 GHz, 23 dB at  
2.0 GHz  
The PE4239 UltraCMOS™ 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.  
• Typical input 1 dB compression point of  
+27 dBm  
• Ultra-small SC-70 package
