Introduction

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 x 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 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 VCOMP switch point voltages, respectively.
