FEATURES
DESCRIPTION
UltraFast 7ns Response
Time 15GHz RF Power
Detector with Comparator
The LTC5564 is a precision, RF power detector for ap-
plications 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 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.
