    Abstract: A variable-frequency resonator has a dielectric strip serving as a main line (1;14) and a dielectric strip serving as a sub line (2;15). A dielectric resonator (3) is disposed therebetween, and a diode board (16) is disposed at an intermediate point of the dielectric strip serving as the sub line (2;15). The electrical length of the sub line (2;15) is switched according to the electrically conductive/open state of the diode (7). With this switching, the resonant frequency of the dielectric resonator is changed. Therefore, a variable-frequency resonator having a high Q value, a variable-frequency oscillator having a high C/N ratio, and a variable-frequency filter having low loss are implemented.

    Abstract: A monolithic high frequency voltage controlled oscillator trimming circuit includes a plurality of capacitance loops (140) selectively connected between a first (120) and second (130) differential input of a voltage oscillator active network (110). A plurality of diodes (159, 160), connected in series with the respective plurality of capacitance loops (140), selectively connect respective capacitance loops (140) between the first (120) and second (130) differential input when forward biased. In a similar fashion, the plurality of diodes (159, 160) selectively disconnect the respective capacitance loops (140) from the first (120) and second (130) differential input when reverse biased. A controller (180) applies a forward biasing voltage to the diode (159, 160) of the selected capacitance loop (140) to connect the capacitance loop (140) to the active network (110) of the voltage controlled oscillator and applies a reverse biasing voltage to the diode (159, 160) of the selected capacitance loop (140) to disconnect the capacitance loop (140) from the active network (110). The diodes (159, 160) used in the capacitance loops (140) form a switch operable at high frequencies and are formed from a bipolar complementary metal oxide semiconductor electro-static discharge protection diode.

    Abstract: Disclosed is a voltage controlled oscillator which is prevented from generating an abnormal oscillation signal and realizes reduction in the number of parts used including a large part, a smaller structure as a whole, and a lower manufacturing cost. This voltage controlled oscillator comprises: an oscillation transistor (1 1 ) which operates by common-base connection and outputs an oscillation signal from the emitter; an amplification transistor (1 2 ) which operates by common-emitter connection and whose base receives the oscillation signal; and a resonance circuit (2) connected to the collector of the oscillation transistor. In the resonance circuit, an inductor (2 1 ) for resonance is connected in a d.c. circuit provided between the collector of the oscillation transistor and the emitter of the amplification transistor, and a capacitor for resonance is connected between the collector of the oscillation transistor and an earth point.
