摘要： The invention relates to a high-frequency oscillator (1) comprising an electric resonant circuit (2), a high-frequency welding system and to a method for controlling the frequency using a high-frequency oscillator, in particular in a high-frequency welding system. Said electric resonant circuit (2) comprises at least one electronic component (3) having an inductance and at least one capacitor (4) having a capacitance. In order to control the frequency of the electric resonant circuit in a fast and wear-resistance manner, at least one additional magnetic coil (6) is associated with the electronic component (3) and can electronically influence the inductance of the electronic component (3).

摘要： A calibration device (CD) is dedicated to a RF band-pass filter (RFF) comprising a means (FM) for filtering a frequency band depending on the value of a control voltage applied by a controllable power supply means (PSM). This device (CD) comprises i) a generator (GM) for feeding the filter means (FM) with a test signal of a chosen frequency, ii) a means (MM) arranged to measure the output power values of the test signal at the filter means output, and iii) a control means (CM) arranged a) to order the power supply means (PSM) to apply successive increasing control voltages as long as the output power value increases, reaches a maximum value and then begins to decrease, then b) to store the first decreasing output power value and the corresponding control voltage, then c) to order the power supply means (PSM) to apply successive decreasing control voltages as long as the output power value increases, reaches said maximum value and then begins to decrease to a last output power value, and then d) to determine a control voltage corresponding to a maximum of the filter output power at the chosen frequency from the stored control voltage and the control voltage applied last and corresponding to the last output power value.

摘要： A method (100) for mechanically tuning a VCO that has a resonant stripline having vias in predetermined locations connected through a circuit board to ground. This includes a step (104) of measuring the operating frequency of the VCO. A following step (106) includes calculating an amount of frequency shift needed to achieve a desired frequency. A following step (108) matches the amount of frequency shift needed to values in a look-up table of frequency shifts versus via locations to determine which vias locations will provide the proper amount of frequency shift. A last step (110) includes mechanically disconnecting from ground the via locations indicated in the third step such that the desired frequency is achieved. This method (100) of tuning allows VCO frequency adjustment after final assembly avoiding problems of frequency shifts that can occur due to the placement of a metal lid on the circuit board after assembly.
