Claim:
1. A resonant circuit with a characteristic impedance stabilized at a chosen value, comprising an input terminal and an output terminal, and at least: a group of N resonators, where N>1, said group of N resonators having a same resonance frequency and a same antiresonance frequency; the group of N resonators configured to provide a variable static capacitance; a first impedance matching element and a second impedance matching element having a non-zero reactance, the first impedance matching element being in series with said group of N resonators, and the second impedance matching element being in parallel with said group of N resonators, said resonant circuit comprising: said first and second values being such that: a triplet of values composed of the static capacitance of said group of N resonators, the impedance of the first impedance matching element, and the impedance of the second impedance matching element being used to determine the following triplet of parameters:
