Title:
INTERACTION APPARATUS EXPANDED TO WIDER BAND
Document Type and Number:
Japanese Patent JPS6420702
Kind Code:
A
Abstract:
PURPOSE: To tune a resonance frequency over a wide frequency band by changing an interaction frequency of a delay line stepwise with a cavity resonance frequency. CONSTITUTION: An inductor L1 is formed by an area formed by walls 11, 12 of a cavity and a capacitor C1 is formed by a gap between the walls 11 and 12. The capacitance C1 is changed by moving a movable member 12 with respect to a stationary member 11 to change the gap and the resonance frequency is changed while keeping the total inductance of the circuit constant. The capacitance C1 and also the capacitance C2 are changed by changing the gap between the members 11, 12 and a delay line is tuned stepwise by the resonance cavity.
