Abstract

PURPOSE:To facilitate the coupling among a cylindrical cavity divided into two axially symmetrically, an oscillation part and a modulation part and to make it easy to adjust their coupling extent, by storing MIC substrates coupling with the cavity in a recess part provided at one side of the cavity. CONSTITUTION:In a recess part provided to the metallic part that corresponds to lid 11b of TM010 cylindrical cavity 11a, MIC substrates 12 and 13 are stored. Substrate 12 provided with oscillating element 16 and dummy load 17 serves as an oscillation part, and substrate 13 with varactor 18 and choke 19 as a modulation part; and tops of those substrates 12 and 13 are projected partially into the cylindrical cavity to couple with the cavity through magnetic field coupling loops 14 and 15. Substrates to be used corresponding to the coupling loops should not have any earth conductor. Then, load (theta) is easily set by varying the sizes of loops 14 and 15 and by shifting MIC substrates 12 and 13 in position.
