Abstract
There is provided a communication system including a transmitter and a receiver, each including a communication circuit unit that processes a high-frequency signal for transmitting data, a band-pass filter, and a high frequency coupler, a distributed constant line connecting the high frequency coupler and the band-pass filter of the transmitter, and a distributed constant line connecting the high frequency coupler and the band-pass filter of the receiver, wherein an electrical length of the distributed constant line of the transmitter is different from an electrical length of the distributed constant line of the receiver.
Claims12
A communication device comprising:
- a communication circuit unit to process a high-frequency signal for transmitting data,
- a band-pass filter,
- a high frequency coupler, and
- a first distributed constant line connecting the high frequency coupler and the band-pass filter, wherein:
- the communication device functions as at least one of a transmitter and a receiver, and a first electrical length of the first distributed constant line is different from a second electrical length of a second distributed constant line connecting a high frequency coupler and a band-pass filter of a transmitter or a receiver at another communication device.
A communication system comprising:
- a transmitter and a receiver, each including a communication circuit unit to process a high-frequency signal for transmitting data, a band-pass filter, and a high frequency coupler,
- a first distributed constant line connecting the high frequency coupler and the band-pass filter of the transmitter, and a second distributed constant line connecting the high frequency coupler and the band-pass filter of the receiver, wherein
