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.

摘要： A bi-directional bridge includes a forward bridge portion, and reverse bridge portion and a shared portion that enables the simultaneous measurement of power flowing in both directions while reducing insertion losses, providing better impedance matching and/or providing improved directionality. In some embodiments, additional attenuation is provided to reduce the common mode rejection requirements of detectors used with the bridge. In other embodiments, multi-tap attenuators and steering circuits may be integrated into the forward and/or reverse bridge portions to reduce common mode signal levels while still maintaining high levels of sensitivity for measuring small input signals.

摘要： A micromechanical sensor for measuring millimetric wave or microwave power, which sensor comprises a wave line for conducting the millimetric or microwave power and a part arranged to move and a fixed electrode, in such a way that the capacitance (C) between the part that is arranged to move and the fixed electrode couples to the wave power advancing in the wave line. According to the invention, the capacitance (C) between the part that is arranged to move and the fixed electrode is divided into at least two portions (C/n), which are located at a distance from each other, in such a way that the wave power advancing in the wave line couples to the portions (C/n) of the capacitance (C) consecutively and experiences the inductive load between the portions (C/n) of the capacitance (C). Thus the frequency band of the sensor can be substantially broadened and the reflective coefficient can be kept reasonably small.
