LTC5564IUD#PBF

LTC5564 is a precision, RF power detector. The RF input signal is peak detected and then sensed by both a comparator and amplifier. The comparator provides a 9ns response time to input levels exceeding VREF along with a latch enable/disable function. The gain selectable operational amplifier provides a 350V/µs slew rate and 75MHz of demodulation bandwidth to the analogue output. VOUTADJ and VREF pins allow for the adjustment of VOUT offset and VCOMP switch point voltages, respectively. It is widely used in applications such as RF signal presence detectors for: 802.11a, 802.11b, 802.11g, 802.15, optical data links, wireless data, modems, wireless and cable infrastructure, 5.8GHz ISM band radios, MMDS microwave links, PA power supply envelope tracking control, fast alarm, envelope detector, ultra-wideband radio, radar detector etc.
