ABSTRACT:
A method and apparatus is disclosed for automatically and exactly tuning a boradband filter. Upon the detection of a tuning change, the filter is automatically switched end to end so that the output terminal of the filter is connected to the radio frequency power source. Radio frequency in this application refers to any signals whose frequency facilitates propagation of data via electromagnetic waves. The input terminal is terminated into a known load such as 50 ohms and C1, an input variable reactance is adjusted until a 90.degree. phase relationship exists between the input resonator and the output resonator's node voltages. These actions set the exact tune condition for the broadband filter. The filter is then automatically reconnected in its normal operating position with its input terminal being connected to the RF power source and its output terminal being connected to its load, such as an antenna, and additional adjustments performed by varying the capacitance of the output capacitance C2 and the coupling capacitance C3.
