Abstract
A communication apparatus includes a transmission path arranged on a substrate, a signal source connected to an input portion of the transmission path, a metal member configured to function as a ground portion for the transmission path and having a space between the metal member and the transmission path, and a termination circuit configured to terminate the transmission path, wherein the termination circuit is arranged on a surface of the substrate on which the metal member is arranged.
Claims10
A communication apparatus comprising:
- a transmission path including two paths configured to be on a single-sided flexible substrate;
- a signal source configured to transmit or receive a differential signal and connected to an input portion of the transmission path;
- a metal member configured to function as a ground portion for the transmission path, and arranged in such a way that a part of the metal member and is separated from the single-sided flexible substrate;
- a termination circuit configured to terminate the transmission path and including a plurality of resistors;
- and
- a conductive member configured to be on the single-sided flexible substrate,
- wherein a first resistor and a second resistor of the plurality of resistors are arranged on a surface of the single-sided flexible substrate on which the metal member is arranged, and the first resistor and the second resistor are connected to the conductive member configured to be on the single-sided flexible substrate, and
- wherein a third resistor of the plurality of resistors is arranged on the surface of the substrate on which the metal member is arranged, and the third resistor is further arranged between the two paths configured to be on the single-sided flexible substrate.
