Problems solved by technology

[0004] However, in the structure described in the above-mentioned documents, since the circuit board on which the diodes are installed is vertically arranged in the direction of the long axis of the dielectric rod, it is not easy to fix the circuit board in the device, and it is easy to tilt, and the actual installation effect is relatively small. Difference
Inserting a high dielectric constant thin plate or setting a gap in the NRD waveguide for matching is inconvenient in design and production
The more the coupler of the NRD waveguide deviates from the frequency that makes the power distribution ratio equal, the easier it is for the power distribution ratio to lose balance

Abstract

The invention provides a line connection structure of which a transmission loss between a dielectric line and a suspend line is reduced, a mixer having the structure, and a transceiver provided with the mixer. A first conductor pattern 51 is disposed in the direction across, almost vertically, first dielectric strips 31a and 31b constituting a first NRD guide. A second conductor pattern 52 is disposed in the direction across, almost vertically, second dielectric strips 32a and 32b constituting a second NRD guide. Protruding conductor patterns 10 and 11 which protrude in the extending direction the dielectric strip are provided at the intersections of the conductor pattern and the dielectric strip, respectively.

Description

technical field [0001] The invention relates to a line coupling structure between a medium line and a suspension line for transmitting signals such as millimeter waves, a mixer with the structure, and a transceiver with the mixer. Background technique [0002] As a diode mounting structure in a non-radiative dielectric line (hereinafter referred to as "NRD waveguide") and a mixer using it, it has been disclosed in "Non-Radiation Using Beam Lead Diodes" written by Kuroki and Yoneyama. Circuit Components of Dielectric Circuits" (C-I, Vol J73-C-I No.2 pp71-76 February 1989). [0003] In this mixer, a coupler is formed by an NRD waveguide, and a circuit board mounted with a diode is vertically inserted into a dielectric rod to couple the diode and the NRD waveguide. [0004] However, in the structure described in the above-mentioned documents, since the circuit board on which the diodes are installed is vertically arranged in the direction of the long axis of the dielectric rod...
