The LTC5564 is a precision, RF power detector for applications in the 600MHz to 15GHz frequency range. The LTC5564 operates with input power levels from –24dBm to 16dBm.

A temperature compensated Schottky diode peak detector, gain-selectable operational amplifier, and fast comparator are combined in a small 16-lead 3mm × 3mm QFN package.

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 V_REF 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.

V_OUTADJ and V_REF pins allow for the adjustment of V_OUT offset and V_COMP switch point voltages, respectively.
