Integrated Device Technology (NASDAQ:IDTI) has introduced a single-pole, double-throw (SPDT) absorptive RF switch for DOCSIS 3.1 networking equipment, the 75-ohm IDT F2970.

"By meeting the requirements of the DOCSIS 3.1 standard, the F2970 can be deployed in a multitude of advanced cable system and other high-performance RF applications," said Duncan Pilgrim, general manager of IDT's RF Division. "The device offers a leading combination of low insertion loss and high isolation, minimizing path loss while preventing cross talk and signal degradation."

The F2970 is designed for high linearity across a frequency range of 5 MHz to 3000 MHz, allowing the switch to be used in both the upstream and downstream. It features composite triple beat (CTB) and composite second order (CSO) of -90 dBc with 77 and 110 channels with output power of 44 dBmV. The device features an operating temperature range of -40 to 105 C, insertion loss of 0.32 dB at 1,200 MHz, and isolation of 68 dB at 1,200 MHz. It operates with a single positive supply voltage and supports 3.3 V logic.

The F2970 is packaged in a 4mm x 4mm 20L QFN package. Samples and volume production parts are available immediately at $0.93 each for 1,000 and $125 for an evaluation board.
