PURPOSE:To realize wide-range oscillation even in a high frequency band by connecting a tuning diode, resonance line, and switch diode in series in terms of alternating current. CONSTITUTION:A resonator part A and an amplification part B are connected together by a coupling capacitor C1, and a tuning voltage BT is applied through a high resistance R1 to one terminal of the coupling capacitor C1 on the side of the resonator part A. Further, the AC series connection circuit of a tuning diode D1, resonance line L1, and switch diode D2 is connected between the ground and intersection I of the high resistance R1 and coupling capacitor C1. Further, a capacitor CrD is connected in parallel to the diode D2 and a switch voltage BS is supplied properly through a high resistance R3 to the intersection of the diode D2 and coupling capacitor C2. Consequently, the wide-range oscillation is realized even in a high frequency range. |
