摘要： A method is provided for evaluating the reliability of an electrical power measuring device for measuring high-frequency electrical power. To build an evaluation system, the measuring device, together with a reference electrical power measuring device, is arranged between a high-frequency power supply device and an artificial reproduction load, which includes an impedance conversion device and a reference load. Using this system, an uncertainty range of an electrical power measured value measured by the measuring device is calculated, according to a prescribed calculation formula, from the electrical power measured value, and a judgment is made as to whether or not the electrical power measured value measured by the measuring device is within the uncertainty range. If it is within the uncertainty range, the measuring device is evaluated as being reliable, while if it is not within the uncertainty range, the measuring device is evaluated as being unreliable.

摘要： A measurement system, for use in RF power measurements, allows an arbitrary Bruene-type RF coupler to be calibrated at a number of different power levels and frequencies with an idealized transfer function being created for each calibration power point. Following calibration, when the coupler is used in an operational (measurement) mode, the DC voltage corresponding to the present power measurement is read, and the discrete idealized transfer functions generated during the power and frequency calibration phases are used to determine a best fit idealized transfer function, which is used in conjunction with the exact DC voltage being measured to create a highly accurate power measurement.

摘要： A high frequency detection circuit detects information about a first high frequency power in a high frequency power source device supplying the first high frequency power having a first frequency and a second high frequency power having a second frequency lower than the first frequency to a load. A third high frequency signal that is a mixed signal of a first high frequency signal having the first frequency and a second high frequency signal having the second frequency is detected by a directional coupler. The third high frequency signal is converted to a fourth high frequency signal having a third frequency between the first and second frequencies using a heterodyne system. A progressive wave power of the first frequency is detected based on the fourth high frequency signal.

摘要： An integrated detector circuit (20) includes first and second gain stages (GS1, GS2). The first gain stage has an input (82) that monitors a high frequency signal (VRFDET) for routing a first detection current (IS1) to a node (60). The second gain stage includes a first current source (PF1) that supplies a bias current (IMAX1) indicative of a predefined amplitude of the high frequency signal. An input of the second gain stage monitors the high frequency signal to route a portion of the bias current to the node as a second detection current (IS2), which is limited to the bias current when the high frequency signal is greater than the predefined amplitude to compensate for a nonlinearity in a transconductance of the second gain stage.
