Features n n n n n n n n LTC5564 Ultra Fast™ 7ns Response Time 15GHz RF Power Detector with parator DESCRIPTION The LTC®5564 is a precision, RF power detector for applications in the 600MHz to 15GHz frequency range. The LTC5564 operates with input power levels from - 24d Bm to 16d Bm. A temperature pensated Schottky diode peak detector, gain-selectable operational amplifier, and fast parator are bined in a small 16-lead 3mm × 3mm QFN package. The RF input signal is peak detected and then sensed by both a parator and amplifier. The parator 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 analog output. VOUTADJ and VREF pins allow for the adjustment of VOUT offset and VP switch point voltages, respectively.
