Title:
BROAD BAND HIGH FREQUENCY AMPLIFIER
Document Type and Number:
Japanese Patent JP3188494
Kind Code:
B2
Abstract:
PURPOSE: To output a high power with a minimum size without revising a coupling point over the entire frequency over a wide frequency range.
CONSTITUTION: Plural distributed constant circuits 4,6 having a coaxial cylinder or its equivalent structure and provided respectively with circuit length adjustment devices 5, 7 are arranged on a common axis 3 in series at an output side of an output vacuum tube 2. Then a matching circuit 4 used for being coupled with a load is adopted for one of the distributed constant circuits and a tuning circuit 6 to decide a prescribed frequency band is adopted for the rest single or plural distributed constant circuits.
