PURPOSE:To facilitate the adjustment for a resonance frequency, by arranging plural metallic pieces oppositely to microstrip resonance lines. CONSTITUTION:An oscillating circuit consists of a transistor 1, a microstrip resonance line 2 with the end opened, metallic pieces 10-12 for the adjustment of the resonance frequency of the resonance line 2, and microstrip lines 5-7. If the metallic piece 10 provided near an end part 2b of the resonance line 2 is moved, the resonance frequency is much changed. If the metallic piece 12 provided near a middle point 2a is moved, the resonance frequency is less changed. Thus, plural metallic pieces are provided to adjust the resonance frequency easily. |
