Title:
MICROWAVE DELAY CIRCUIT
Document Type and Number:
Japanese Patent JP3129506
Kind Code:
B2
Abstract:

PURPOSE: To provide a high wave delay rate and a high characteristic impedance on a circuit and to miniaturize the circuit by connecting each of 1st transmission lines and each of 2nd transmission lines alternately in the extending connection direction of the 1st and 2nd transmission lines in cascade.
CONSTITUTION: Each of plural 1st transmission lines 100 is constituted of a tri-plate microstrip line having a comparatively low capacitive characteristic impedance ZL and having a 1st longitudinal cross section that the width Wst of a center conductor 6 is wider than the width Ws of a strip conductor 6a by providing two projection conductors 6b protruded from the strip conductor 6a to the conductor 6. Each of plural 2nd transmission lines 200 is constituted of an elevated coplaner line having a comparatively high inductive characteristic impedance ZH and having a 2nd longitudinal cross section. Then each of the 1st transmission lines 100 and each of the 2nd transmission lines 200 are connected alternately and in the extending connection direction of each of the transmission lines 100, 200 being a direction in parallel with the longitudinal direction of the center conductor 6 in cascade.
