Package Type RFC RF1 RF2 C1 75 75 75 C2 CMOS Control Driver The PE4280 is an UltraCMOS™ Switch designed for CATV applications, covering a broad frequency range from DC up to 2.2 GHz. This single-supply SPDT switch integrates a two-pin CMOS control interface. It also provides low insertion loss with extremely low bias requirements while operating on a single 3 V supply. In a typical CATV application, the PE4280 provides for a cost effective and manufacturable solution when compared to mechanical relays. The PE4280 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. Product Specification 75 Ω SPDT CATV UltraCMOS™ Switch 5 MHz - 2.2 GHz Product Description Figure 1. Functional Diagram PE4280 Features 75 Ω characteristic impedance Integrated 75 Ω terminations CTB performance of 85 dBc High isolation 60 dB at 1 GHz Low insertion loss: typically 0.5 dB at 5 MHz, 1.1 dB at 1 GHz High input IP3: 50 dBm CMOS two-pin control Single +3 V supply operation Low current consumption: 8 μA Unique all off terminated mode 4 x 4 x 0.85 mm QFN package Table 1.
