7 GHz precision RF detector includes a fast comparator

3 May 2006 Analogue, Mixed Signal, LSI

Linear Technology claims that its new LTC5536 RF power detector is the first to include a fast comparator. The device combines wide frequency range operation and low power in a small solution that allows precise detection of an RF signal.

The LTC5536's voltage output is compared against a DC voltage threshold that is set by the user. The comparator output transitions when the RF input level goes above or below the threshold point. The device is well suited for detecting the presence of RF signals in 802.11 and 802.16 networks, optical data links, wireless data modems, WiMAX and cellular basestations and cable headends. It can also be used as an RF power monitor or envelope detector in RF ID tag readers.

The device operates over a wide RF frequency range of 600 MHz to 7 GHz, supporting multiband operation. It incorporates temperature compensation circuitry for stable and accurate RF detection over the full range of temperature extremes. The device's on-chip comparator has a fast 20 ns response time - sufficient to be used for recovery of bit stream data. The integrated functions eliminate the need to glue many discrete components together, saving on circuit board space.

The LTC5536 is packaged in a 6-lead ThinSOT package and operates from a single 2,7 V to 5,25 V supply, drawing a typically 2,1 mA (quiescent).
