4273-02

Product Specification PE4273 Product Description The PE4273 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. It offers a simple alternative solution to pin diode and mechanical relay switches. The PE4273 SPDT Broadband 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. SPDT Broadband UltraCMOS™ DC – 3 GHz RF Switch Features • Single-pin or complementary CMOS logic control inputs • High ESD tolerance of 1.5 kV • Low insertion loss: 0.50 dB at 1000 MHz, 0.65 dB at 2000 MHz • Isolation of 34.5 dB at 1000 MHz, 25 dB at 2000 MHz • Typical input 1 dB compression point of +32 dBm Figure 1.
