摘要： Disclosed is a channel-selective RF power sensor having a coupler and a channel-selective power measurement circuit. The said coupler is configured to obtain a sample of energy travelling on a main transmission line and provide the sample of energy to the channel-selective power measurement circuit. The sample of energy has a channel of interest. The channel-selective power measurement circuit is configured to measure RF energy information for the channel of interest in the sample of energy. Also disclosed is a method of measuring RF energy information for a channel of interest. The method includes providing a channel-selective RF power sensor and a main transmission line and obtaining a sample of energy from the main transmission line using a coupler of the channel-selective RF power sensor.

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.
