Abstract
A connecting structure for connecting two oscillator circuits to an amplifier. The oscillator circuits are provided on one surface of a printed circuit board and include two dielectric resonators. The amplifier circuit is provided on the other surface of the printed circuit board for selectively amplifying oscillatory outputs from the oscillator circuits. The dielectric resonators are fixed to a metal plate mounted on the printed circuit board, and the amplifier circuit is located at a position opposite to the metal plate.
