Abstract
The invention relates to a resonator (200,300) with variable resonance frequency, intended for connection to an amplifier, thus forming an oscillator, said resonator comprising a resonator circuit (205,305) for deciding the resonance frequency of the resonator and the oscillator, said resonator circuit comprising an inductance (L), a variable capacitance (C.sub.j), and means (V.sub.tune) for varying the capacitance. The resonator also comprises connection means (C.sub.1, C.sub.k ; C.sub.1, C.sub.k, C.sub.2) for connecting the resonator to an amplifier. The resonator is provided with means (V.sub.tune) for varying the capacitance of the connection means in proportion to the variation of the capacitance (C.sub.j) of the resonator circuit. Preferably, the means (V.sub.tune) for varying the capacitance (C.sub.k) of the connection means are arranged such that an essentially constant relationship (C.sub.k /C.sub.j) is maintained between the capacitance (C.sub.k) of the connection means and the first capacitance (C.sub.j) of the resonator across all resonance frequencies.
