    摘要: Bei Einseitenbandmischern, die üblicherweise aus zwei Gegentakt­mischern bestehen, die mit 90° Phasenunterschied in den Oszilla­tor- und Zwischenfrequenzanschlüssen betrieben werden, werden hohe Anforderungen an Nebenwellenfreiheit gestellt. Die erste Oszillatoroberwelle stellt dabei das stärkste Störsignal dar. Besonders problematisch ist dies dann, wenn dem Mischer ein Ver­stärker folgt, wie z. B. bei Richtfunksendern. Die erfindungsgemäßen Lösungen sehen eine solche Zusammenschal­tung der beiden Gegentaktmischer vor, daß sich die ersten Oszil­latoroberwellen entweder auslöschen oder mittels eines Ma­gischen-T's auf einen Abschlußwiderstand geführt werden.

    摘要: A frequency converter circuit used for a receiver for satellite broadcast. Local oscillation signals are supplied from a single local oscillation circuit (8) to mixer circuits (11a,11 b) of electric signal processing circuits (4, 5) of two or more systems, and a mixer diode (27) of each ofthe mixercircuits (11a, 11 b) is biased with a direct current. Even the mixer diode (27) of the signal processing circuit of the system that is not in operation is biased with the direct current at all times, presenting advantage in regard to stable operation, small size, light weight, and low cost.

    摘要: A finline detector (100 or 110) comprises a dielectric substrate-mounted circuit disposed within a millimeter waveguide, said substrate circuit comprising a substrate (114) with a diode (224) mounted thereon in series with the waveguide (16). The mounting of a diode (224), which may have a characteristic impedance substantially lower than the characteristic impedance of a realizable finline, in series with the waveguide transmission line minimizes sensitivity to the high capacitance and therefore low impedance realizable with such a detection diode. Furthermore, the transmission line may be terminated more easily in a wideband termination (50), thus increasing the effective bandwidth of operation of the detector. Two representative embodiments of the invention are, for example, an unbalanced detector (100) and a balanced detector (110). Each embodiment includes a detection device, namely a diode (224, 324), coupled in series with the finline transmission line (101). Capacitance means (34,134,36,136,38,138) are also provided.

    摘要: Mélangeur plan équilibré d'ondes millimétriques possédant un organe optique permettant le couplage d'ondes à haute fréquence au circuit mélangeur (8). L'organe de couplage optique peut comprendre une lentille diélectrique (32) et notamment une lentille diélectrique sphérique. La lentille sphérique non seulement assure un gain de l'énergie à haute fréquence mais satisfait aux sévères exigences de tolérance et aux restrictions concernant la taille qui se posent lors de la fabrication de guides d'ondes conventionnels pour des ondes millimétriques comprises dans la plage entre 100 et 300 GHz.

    摘要: A microwave integrated circuit frequency converter includes a first filter (30) for a signal frequency and a second filter (32) for a local oscillator frequency connected at one terminal thereof with one terminal of the signal frequency filter (30) by a line (38), (40) having a predetermined electrical length. A parallel stub line (42) is short-circuited at one end thereof. A diode (34) is connected at its one end to a third filter (36) which is adapted to reflect the signal and local oscillator frequencies while passing an intermediate frequency. The parallel stub line (42) and diode (34) are connected at their other ends to a specific mixing point P on the connecting line (38, 40) at which the impedance is opened for the signal frequency when the local oscillator frequency filter (32) is seen from the signal frequency filter (30) side and the impedance is opened for the local oscillator frequency when the signal frequency filter (30) is seen from the local oscillator frequency filter (32) side.
