Suitable for broadband consumer applications including CATV, DTV, multituner DVR, set-top boxes, PCTVs, and video game consoles, the 75-Ω PE42750 RF switch features an isolation of 63 dB typ at 1 GHz. Isolation levels are maintained in the unpowered state in compliance with the FCC 15.115 standard for CATV-to-antenna isolation. During unpowered operation, the ports are terminated to prevent reflected signals between the terrestrial and cable antennas.
The switch covers a broad frequency range from 5 to 2,200 MHz with a single positive supply and CMOS control, and delivers low insertion loss of 0.7 dB at 5 MHz and 1.0 dB at 1,000 MHz. Housed in a 3 x 3-mm 12-lead QFN package, the part has a high IIP3 of 47.5 dBm at 5 to 2,200 MHz and an ESD performance of 2,000 V HBM on all ports. ($0.57 ea/1,000 — samples available now.)
