Product Specification PE4270 SPST CATV UltraCMOS Switch Product Description 1 - 3000 MHz The PE4270 is a is a high-isolation switch designed for CATV Features applications, covering a broad frequency range from 1 to 3000 Integrated 0.25 watt terminations MHz. This single-supply SPST switch offers a single-pin CTB performance of 90 dBc CMOS control interface with industry leading CTB High isolation: 90 dB at 5 MHz, 63 dB performance. It also provides low insertion loss, high isolation at 1000 MHz and extremely low bias requirements while operating on a single 3-volt supply. In a typical CATV application, the PE4270 Low insertion loss: 0.5 dB at 50 MHz, provides for a cost effective and manufacturable solution vs. 0.70 dB at 1000 MHz mechanical relays. High input IP2: >80 dBm CMOS/TTL single-pin control The PE4270 is manufactured on Peregrines UltraCMOS process, a patented variation of silicon-on-insulator (SOI) Single +3-volt supply operation technology on a sapphire substrate, offering the performance Extremely low bias: 8 A 3 V of GaAs with the economy and integration of conventional Available in a 6-lead DFN package CMOS.
