CIRCUIT SUBSTRATE AND BRANCH CIRCUIT

摘要

A circuit substrate includes a substrate body, an input signal line conductor with which the substrate body is provided and included in an input path, a first mounting portion provided on a main surface of the substrate body, included in a first output path and on which a high-pass filter including a lumped-parameter element is mounted, at least one first output signal line conductor with which the substrate body is provided and included in the first output path, and a second mounting portion provided on the main surface of the substrate body, included in a second output path and on which a low-pass filter including a lumped-parameter element is mounted. The first output signal line conductor provided farthest upstream in a signal propagation direction is connected to the input signal line conductor via a first lumped-parameter element mounted on the main surface of the substrate body.

1. A circuit substrate for use in a branch circuit that includes an input path, a first output path including a high pass filter and connected to the input path, and a second output path including a low pass filter and connected to the input path, the circuit substrate comprising:
a substrate body; an input signal line conductor with which the substrate body is provided and which is included in the input path; a first mounting portion provided on a main surface of the substrate body, included in the first output path and on which the high pass filter is mounted; at least one first output signal line conductor with which the substrate body is provided and which is included in the first output path; and a second mounting portion provided on the main surface of the substrate body, included in the second output path and on which the low pass filter is mounted; wherein the first output signal line conductor provided farthest upstream in a propagation direction of a signal is connected to the input signal line conductor via a first lumped-parameter element mounted on the main surface of the substrate body.
