Product Specification
PE4272
SPDT Broadband UltraCMOS™
DC – 3 GHz RF Switch
Product Description
The PE4272 RF Switch is designed for the TV tuner, PCTV, set
top box, DTV, DVR and general broadband applications. This
device offers industry leading broadband linearity, 1.5 kV ESD
tolerance and a simple CMOS interface. The device offers a
simple alternative solution to pin diode and mechanical relay
switches.
Features
• High ESD tolerance of 1.5 kV
• Single-pin CMOS logic control
• Low insertion loss: 0.5 dB at 1000 MHz,
0.6 dB at 2000 MHz
• Isolation of 43 dB at 1000 MHz, 33.5 dB
The PE4272 SPDT High Power 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.
at 2000 MHz
• Typical input 1 dB compression point of
+32 dBm
• Small 8-lead MSOP package
