Abstract: An impedance matching circuit for providing a lossless target signal transmission and rejecting image signals of heterodyne and super-heterodyne transceiver. The impedance matching circuit includes a grounded metal membrane, a first microstrip line connected with an input circuit, a second microstrip line connected with an output circuit, and a third microstrip line connected with either the first microstrip line or the second microstrip line. The first microstrip line is not connected with the second microstrip line, and the length of the third microstrip line is equal to a quarter wavelength of an image signal. When the target signal and the image signal transmit to the impedance matching circuit, the image signal will bypass to a grounded metal membrane, and the target signal will transmit to the output circuit without signal decay through electromagnetic coupling of the first microstrip line and the second microstrip line.

Abstract: The invention comprises a high-frequency low-pass filter (200) The filter utilizes distributed capacitance and inductance elements (221-227) which are realized using a homogeneous and relatively rigid conductive part (220). The conductive part is located mainly air-insulated in an enclosed metal housing (210) which serves as a ground conductor for the signal. The housing comprises conductive partition walls (212-214) to prevent coupling between adjacent capacitive elements. The advantages of the construction include good power handling capacity, good breakdown characteristics, small losses and low manufacturing costs, among other things.

Abstract: A band pass distributed element filter having real and imaginary transmission zeros by sequentially connecting half wavelength microstrip resonators and adding a cross coupling circuit has been difficult to implement as a planar circuit on the same plane, since the cross coupling circuit crosses one of the resonators. The distributed element filter is constructed by sequentially connecting n half wavelength microstrip resonators (n is an even number equal to or more than 4) each formed from a straight or hairpin microstrip line, wherein the number of straight microstrip lines and the number of hairpin microstrip lines are both odd, and wherein quarter wavelength straight microstrip lines for external circuit connection are coupled to the first and n th resonators, respectively, and a cross coupling circuit is connected to the microstrip lines of these resonators or to the ends coupled to the microstrip lines. A band pass filter can thus be realized using only a planar circuit by preventing the cross coupling circuit from crossing any one of the resonators.
