Title:
COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/187241
Kind Code:
A1
Abstract:
A communication device according to the present invention comprises: a communication connector (12); a communication control circuit (11) that controls communication which passes through the communication connector (12); and a common mode filter (13) that is connected to the communication control circuit (11) and the communication connector (12), and that relays communication. Defining λ as a wavelength corresponding to a clock frequency of an electrical signal transmitted by the communication control circuit (11), the electrical length of a signal path, where resonance is generated by a reflected wave resulting from the abovementioned electrical signal being reflected by the common mode filter (13), is closer to an even multiple than an odd multiple of λ/2.
