摘要： A microwave mixing circuitry has a plurality of microwave signal input terminals, a local oscillator for outputting a local oscillation signal for the purpose of generating an intermediate frequency signal from the microwave signal input by the microwave signal input terminals, and a plurality of field effect transistors (“FET”) for frequency converting. The FET gates are input with the microwave signal input from microwave signal input terminals. The FET drains are input with an output of the local oscillator. A plurality of gate voltage control circuitries control gate voltages of the FETs thereby causing one of the FETs to perform nonlinear operation while turning off another of FETs at the same time.

摘要： An oscillator circuit including a metal plate secured to a dielectric substrate. A micro strip line is mounted on the dielectric substrate. One end of the micro strip line is connected to the gate terminal of a field effect transistor for microwave oscillation and the other end of the micro strip line is grounded to the metal plate via a terminal resistor. A dielectric resonator is secured with an ordinary adhesive to the inner wall of a shield case. Attaching the dielectric resonator to the shield case allows the degree of coupling, defined by the distance between the micro strip line and the dielectric resonator, to be freely set. A tuning screw is screwed through the metal plate and the dieletric substrate opposite to the dielectric resonator. The microwave oscillation circuit can be used with a down converter.

摘要： A microwave oscillator includes a substrate having a circuit pattern on the top surface, a thin copper foil covering the bottom surface, and a hole. An electronic component is mounted to the top surface of the substrate. A metal plate is attached to the bottom surface of the substrate thereby closing the bottom of the hole. A dielectric resonator is attached to the metal plate through the hole. Since the dielectric resonator is attached to the metal plate by soldering, the bond between the dielectric resonator and the metal plate is stronger and more stable than that achieved by using a conventional adhesive. This enhances the reliability against temperature changes; mechanical impact or humidity.

摘要： In a microwave multistage amplifier, a shield casing (8) has a partition plate (7) integrally moulded with and disposed in the casing (8); microwave amplifiers (5, 6) are arranged on a dielectric substrate so as to locate the partition plate therebetween; and an upper cover plate (11) is provided which can be screwed to partition plate (7). By virtue of the above-mentioned arrangement, it becomes possible to strictly separate rooms defined in the casing from each other and suppress generation of a surface wave mode of the microwave propagation on the dielectric substrate, thereby assuring an isolation between the amplifiers.

摘要： A microwave oscillator for inducing parallel feedback from collector to base and obtaining a stabilized oscillation output is realized by connecting MSL A with released end to a base terminal of a transistor, connecting MSL B to its collector terminal, and disposing a DR closely to the MSL A and B to couple them electromagnetically. The length between the released end and the position of MSL A which is closest to the center of DR is set to λg1/4 (λg1 is the guide wavelength in the MSL A), and HIL is merely connected to this position as a bias supply line to the base terminal. This structure does not require the choke circuits which occupied a relatively wide area on the conventional circuit board, and a small and stable microwave oscillator having excellent phase noise characteristics, and a low-noise converter for receiving satellite signal by using the same are realized.

摘要： A microwave mixing circuit of a small size for selecting a signal to be received out of plural microwave signal inputs, and converting it to an intermediate frequency signal, and a down converter comprising it are provided. A microwave input signal within a band of 12 GHz applied to one microwave signal input unit is guided through a bias terminal from a comparator into a mixer diode to which a bias current is supplied, and is converted in frequency by the mixer diode. A microwave input signal applied to other microwave signal input unit is guided through the bias terminal from the comparator into a mixer diode to which bias current is not supplied, and is hence not converted in frequency by the mixer diode. As a result, only an intermediate frequency signal of 1 GHz band corresponding to the former microwave signal appears at the intermediate frequency signal output terminal.
