摘要： A system and method for monitoring RF power is described. In one embodiment the system samples RP power that is generated by an RP generator to obtain RF signals that include information indicative of electrical characteristics at a plurality of particular frequencies that fall within a frequency range. The RF signals are digitized to obtain a stream of digital RF signals that include information indicative of electrical characteristics at the plurality of particular frequencies, and the information indicative of electrical characteristics is successively transformed, for each of the plurality of particular frequencies, from a time domain into a frequency domain.

摘要： A square cell comprises first and second bipolar transistors each having an emitter, collector and base, the bases of the transistors being connected for receiving an input voltage, and first and second resistors in series with the first and second bipolar transistors respectively and with a source of reference voltage. The collectors are commonly connected to an output node to supply an output current having a component proportional to the square of the input voltage. Enhanced square law conformance may be produced by adding further pairs of bipolar transistors to the cell, with offset voltage elements coupled between bases of successive transistors on each side of the cell.

摘要： A Microwave power detector is coupled to a rectangular waveguide with a sidewall replaced by an uniform metallization on a bottom face of a FR4 dielectric substrate screwed to the waveguide. Two irises aligned along a common line parallel to the lines of magnetic field inside the waveguide, are etched inside the metallization acting as sidewall. Two microstrips are laid down on the upper face of dielectric substrate, each one intersects a respective iris orthogonally in the middle point. The two microstrips are connected to ground at one end immediately beyond respective irises, and are spaced substantially quarter wave apart calculated at the centre of the operating frequency band (15-18 GHz). Besides, the two microstrips are quarter wave long in order to show an open circuit impedance at the other end connected to a respective voltage detector including a Schottky diode in series to a resistor. At midpoint of the connection line between the two serially connected voltage detectors a voltage Vsum is read with high impedance. Vsum is the average of the two detected voltages, it is indicative of the signal power travelling across the waveguide and it results substantially insensitive of standing-wave pattern ( fig.12 ).
