Abstract

PURPOSE: To reduce reflection loss by a method wherein a specified relation is held between the characteristic impedance of metal housing barrier terminal area and the impedance of circuits on the insulator inside the housing, and circuit terminals are connected with central conductors of barrier terminal, then grounded through capacity.
CONSTITUTION: When the circuit impedances on input and load are ZΩ, the characteristic impedance Z0Ω is specified as Z0≥Z. A given circuit is converted to capacitive by a discontinuous capacity C1 between the input connection and grounded electrode and a connected capacity C2. The circuit is made inductive by inserting a distributed line with Z0Ω in length, l. Then, the circuit is again converted capacitive ZΩ by using discontinuous capacity C3 produced at the load connection and a capacity C4. The relation Z0≥Z held in this way facilitates the matching between the circuits at both sides of the barrier. If the capacities C2 and C4 are given a value greater than 10 times the parasitic capacity C1 and C3, it elimintaes the need for considering the distribution of the parasitic capacity, and provides a between-stage barrier terminal with extremely small reflection loss.
