摘要： Disclosed is a capacitive non-directional coupler having a non-directional coupler printed circuit board (PCB) and a capacitive attenuator. The non-directional coupler PCB includes a coupler section configured to carry energy travelling on a main transmission line. The non-directional coupler PCB and the capacitive attenuator are configured as a capacitive voltage divider, and provide a sample of the energy on the main transmission line. Also disclosed is a method for measuring for measuring RF power using an RF power sensor having the capacitive non-directional coupler that includes with the non-directional coupler printed circuit board and the capacitive attenuator. Also disclosed is an RF power metering system that includes an RF power sensor having the capacitive non-directional coupler.

摘要： Disclosed is a radio frequency (RF) power calorimeter having a load electrically coupled to a RF input, a variable low-frequency power source electrically coupled to the load and configured to apply low-frequency bias to the load. The RF power calorimeter includes a thermal medium thermally coupled to the load. Additionally, the RF power calorimeter includes an outlet temperature sensor thermally coupled to the thermal medium, the outlet temperature sensor being positioned to measure the temperature of the thermal medium due to heating by the load. The RF power calorimeter also has circuitry configured to use temperature measurements of the thermal medium in thermal contact with an RF load in combination with the low-frequency bias to measure average power of an RF source electrically coupled to the RF input. Also disclosed in a method of measuring RF power using the RF power calorimeter.

摘要： The invention provides an in-line power monitor for an RF transmission line that is capable of being calibrated in-line during live conditions at the exact power level and frequency where it is used. This device uses forward and reflected directional couplers and a non-directional coupler to sample the RF voltage on the transmission line. The RF voltage of the forward and reflected channels are each split into two paths, one going to a test port and the other leading to additional circuitry which prepares the signals of the forward and reflected channels for output to power displays. Additionally, the monitor allows the user to compensate for any voltage offsets introduced by various circuitry components. Further, the monitor also allows to user to individually calibrate the output of the forward and reflected channels by applying an adjustable gain ratio correction to each channel.
