摘要： There is provided a frequency tunable oscillator that has less degradation of oscillation characteristics due to a parasitic reactance component or the like without mounting therein a lumped constant element such as a variable capacitance element. The frequency tunable oscillator includes a negative resistance element and a resonator which together form a feedback circuit. The frequency tunable oscillator further includes in at least a part of the feedback circuit, a distributed constant material so configured as to have a distributed constant such that an electrical length in the resonator is modulated, and a modification means for externally modifying the distributed constant material, wherein the oscillation frequency can be varied through the external modification by the modification means.

摘要： An electronic device (2) is made from a first substrate (22) with device circuitry (32) including an inductor (42) and a second substrate (24) with inductance adjustment circuitry (60) including a number of other inductors (62). The substrates (22, 24) are assembled together to be opposite one another. The other inductors (62) are arranged to provide a selection of different mutual inductance relationships relative to the inductor (42). These relationships are selectable during operation of the device to provide a variable inductance in the device circuitry (32).

摘要： Dargestellt und beschrieben ist ein Mikrowellen-Sensor mit einem selbstmischenden Oszillator, mit einer Sende- und Empfangsantenne (9), mit einer Impedanz, die zwischen die Strom- bzw. Spannungsversorgung und den Oszillator geschaltet ist, und mit einer Auswerteschaltung, wobei der selbstmischende Oszillator sowohl das Sendesignal erzeugt als auch das Sendesignal mit dem Empfangssignal mischt und das niederfrequente Mischprodukt (Doppler-Signal) an der Impedanz abgegriffen und der Auswerteschaltung zugeführt wird.
Der Mikrowellen-Sensor weist dadurch nur einen geringeren Energieverbrauch auf, wobei der Mikrowellen-Sensor auch kostengünstig herstellbar ist, daß der selbstmischende Oszillator als Gegentaktoszillator mit zwei Transistoren (7,8) ausgebildet ist.
