Abstract: An electronically tunable solid-state microwave frequency source comprises a transmission-absorption filter incorporated within a magnetic structure. The transmission-absorption filter is employed with a tunable solid-state oscillator and tunable solid-state multiplier to provide a continuously tunable microwave signal source with enhanced spurious signal attenuation over a multiple-octave tuning range. The filter structure comprises a sphere of monocrystalline garnet such as yttrium iron garnet (YIG) and two coupling loops disposed in the field region of an adjustable field DC magnet. The coupling loops are disposed orthogonal to the magnetic field and to each other. In a specific embodiment the first coupling loop is operative to receive at its input the fundamental frequency signal and at its output is grounded, and the second coupling loop is operative to receive a harmonic input signal at its input and to convey a desired output signal at its output. The magnetic sphere of the transmission-absorption filter typically shares the magnetic field of the YIG sphere used to produce the output of the tuned oscillator. The transmission-absorption filter is incorporated into a source including a switch, a fundamental frequency amplifier and a harmonic frequency amplifier.

Abstract: The present invention relates to a voltage controlled tuning circuit for tuning a resonance frequency of an oscillator, comprising a voltage controlled variable capacitance means (11;45), a first and second inductor means (12,13;46,47) connected in parallel to each other and parallel to the variable capacitance means (11;45), and a first band switch means (14;48) for the first inductor means (12;46) and a second band switch means (15;49) for the second inductor means (13;47) for band switching the resonance frequency. The tuning circuit according to the present invention is less sensible in view of the tolerances of its elements, so that the tuning of the resonance frequency is more precise. Further, the tuning circuit according to the present invention can be operated in the UHF- or VHF-band without the necessity of using expensive circuit elements.

Abstract: A voltage-controlled oscillator and a method capable of precisely adjusting a frequency shift amount are provided irrespective of a fluctuation in characteristics of elements such as a strip-line. A center tap 19 is formed in a strip-line 16 of a resonator. A switching element 20 is connected to the center tap 19, and this switching element 20 is turned ON, so that the center tap is shortcircuited to the ground so as to vary the oscillating frequency. A slit A1 is conducted in the vicinity of the center tap 19 along the strip-line 16 and directed toward a shortcircuited end 17 of the strip-line, so that a frequency shift amount is adjusted. Also, a slit B1 is conducted in the vicinity of the shortcircuited end 17 along the strip-line 16 and directed toward the center tap 19, so that a frequency shift amount is adjusted. Also, trimming points are provided on the side of a hot terminal 18 from the center tap 19, and also provided on the side of the shortcircuited end 17 from the center tap 19, and further a slit is conducted along an intersecting direction of the strip-line 16, so that a shift amount is adjusted.

Abstract: The oscillator having a tunable resonant circuit has a switch (SD) for expanding the tuning range, which is connected in series with two coils (L1a, L1b) jointly determining the oscillation frequency of the resonant circuit. A further coil (L2b), which is coupled to the resonant circuit in the region of the switch (SD), is used to supply a switching voltage (US) for the switch. In this arrangement, the other end of this third coil (L2b) is coupled to a reference potential (G), with a capacitor (C6), which acts as a short circuit for radio-frequency purposes, decoupling the switching voltage (US) from the reference potential (G). Since the switching voltage (US) is in this case coupled to an oscillator circuit node which is earthed for radio-frequency purposes, it is of no significance in this case which resistor is used to couple the switching voltage. This means that the resonant circuit is not resistively damped by the connection of the switching voltage.
Coupled to the other end of the switching diode is a further component (L2a), preferably a fourth coil, which has the same inductance as the third coil (L2b), in order to dissipate the switching voltage. The first two coils are advantageously of the same size, so that this circuit coil jointly determining the oscillation frequency is earthed by the third coil exactly at its centre. This means that the quality factor and the oscillation properties of the resonant circuit are not adversely affected.
Circuits of this type are used, in particular, in television sets to receive the lower and upper VHF bands.

Abstract translation: 具有可调谐谐振电路的振荡器具有用于扩展调谐范围的开关（SD），该开关与两个线圈（L1a，L1b）串联连接确定谐振电路的振荡频率。 在开关（SD）的区域中耦合到谐振电路的另一个线圈（L2b）用于为开关提供开关电压（US）。 在这种布置中，该第三线圈（L2b）的另一端通过电容器（C6）与参考电位（G）耦合，电容器（C6）用作射频目的的短路，去耦合开关电压（US） 从参考电位（G）。 由于在这种情况下，开关电压（US）耦合到用于射频目的接地的振荡器电路节点，所以在这种情况下使用哪个电阻器来耦合开关电压是没有意义的。 这意味着谐振电路不会通过开关电压的连接阻抗。 耦合到开关二极管的另一端是为了耗散开关电压而具有与第三线圈（L2b）相同的电感的另一部件（L2a），优选地是第四线圈。 前两个线圈有利地具有相同的尺寸，使得共同确定振荡频率的该电路线圈由第三线圈正好在其中心处接地。 这意味着谐振电路的品质因数和振荡特性不会受到不利影响。 特别是在电视机中使用这种类型的电路来接收下部和上部VHF频带。
