Abstract
A meter connects to the input of a thermocouple-based RF signal power detector. The apparatus can sense its own load resistor DC impedance, so it can detect both aging in and damage sustained through overload to the RF dissipation element.
Claims7
A RF signal power detector comprising:
- a Kelvin type meter;
- and
- a RF power detector including thermocouples, having a RF input;
- wherein the meter connects to the input of the RF power detector.
