摘要： An apparatus for converting frequency which is used as a converter which, for example, converts a microwave signal received from a satellite broadcast into a signal of a lower frequency, comprises a circular waveguide (12) into which a signal is supplied, a rectangular waveguide (14) which is provided at its final end with a rectangular waveguide-to-microstrip line converter (15), and a circular-to-rectangular waveguide converter (13) connecting between the circular waveguide (12) and the rectangular waveguide (14). The diameter of the circular waveguide (12) is set so that the cut-off frequency of the circular waveguide (12) is lower than the frequency of the received signal and higher than a local oscillation frequency, so that the circular waveguide (12) can act as a high-pass filter, to satisfy noise factor characteristics and increase the image-noise ratio, as well as reduce leakage of the local oscillation signal.

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, 11b) of electric signal processing circuits (4, 5) of two or more systems, and a mixer diode (27) of each of the mixer circuits (11a, 11b) 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 conductive strip (1) of an MSL is connected with the internal conductor of a coaxial line provided with a metallic case (3) as its external conductor, via a through hole (9) bored in a dielectric substrate (2) from an MSL grounding surface (11) which is provided on the dielectric substate (2). A ring-like protruding part (7) is formed on the metallic case and is in contact with the grounding surface (11). Thereby, the external conductor of the coaxial line is reliably in contact with the MSL grounding surface (11). Since there is no mismatching part, the loss and the deterioration of VSWR in the MSL converting part and the coaxial line can be prevented, and desirable characteristics are obtained.
