IPC: H03F1/02
Filed: 1992-11-25
Abstract: PURPOSE:To provide a coaxial amplifier which can easily be assembled in a compact and light-weight structure and can ensure the high efficiency and high gains. CONSTITUTION:The coaxial lines consisting of the outer conductors 1 and 12, the circular dielectrics 2 and 13, and the center conductors 3 and 14 are used as an input terminal and an output terminal respectively. Then the unit amplifiers consisting of the active elements 7 and the matching circuit 8 are radially arranged in both input and output terminals from the conductor 14. In such a constitution of an amplifier, a cut-off conductor 22 is provided between the conductor 3 of the input terminal and the conductor 14 of the output terminal and connected electrically to both conductors 1 and 12 and then separates electromagnetically the input terminal from the output terminal. The conductor 22 includes a piercing line 24 which connects the output signal of each amplifier 9 to the output terminal and a dielectric 23 which insulates and supports the line (linear conductor) 24. Furthermore the signal transmission loss can be reduced by the line 24 consisting of a microstrip or a coaxial line.
