Product Specification  
PE4246  
Absorptive SPST UltraCMOS™  
RF Switch: DC - 5000 MHz  
Product Description  
The PE4246 RF Switch is designed to cover a broad range of  
applications from DC to 5000 MHz. It is non-reflective at both  
RF1 and RF2 ports. This SPST switch integrates a single-pin  
CMOS control interface, and provides low insertion loss while  
operating with extremely low bias from a single +3-volt supply.  
In a typical application, the high isolation PE4246 can replace  
multiple RF switches of lesser isolation performance. It is  
offered in a small 3x3 mm DFN package.  
Features  
• Non-reflective 50-ohm RF switch  
• 50-ohm (0.25 watt) terminations  
• High isolation: 55 dB at 1000 MHz,  
48 dB at 3000 MHz  
• Low insertion loss: 0.8 dB at 1000 MHz,  
0.9 dB at 3000 MHz  
• High linearity: +33 dBm input 1dB  
The PE4246 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.  
compression point  
• CMOS/TTL single-pin control  
• Single +3-volt supply operation  
• Extremely low bias: 33 µA @ 3 V  
• Available in a 6-lead DFN package
