Abstract

PURPOSE:To obtain the frequency selectivity, by constituting the directional coupler using the mutual induction of the inductance consituting the resonance circuit. CONSTITUTION:A primary side is the series resonance circuit consisting of the capacitor C1 and inductance L1 and has the frequency selectivity. The mutual inductance M is in existence between the inductance L2 at a secondary side and the inductance L1 at the primary side. Only the signal (e) selected with the series resonance circuit at a primary side is detected at a secondary side. To obtain the directivity, the relation of M/C<2>=R<2> must be satisfied among the mutual inductance M, coupling capacitor C2 between a primary and secondary sides and the termination resistor R.
