Abstract
A communication circuit includes a first transfer circuit that includes a first transmitter circuit, and a second transfer circuit that includes a second transmitter circuit that can transmit a signal simultaneously with the first transmitter circuit. The second transmitter circuit is configured to be placed in a transmission halt state when transmission power of the second transmitter circuit resulting from being decreased by a predetermined value is lower than or equal to a threshold.
Claims3
A communication circuit comprising:
- a first transmitter circuit;
- and
- a second transmitter circuit configured to transmit a signal simultaneously with the first transmitter circuit,
- wherein the second transmitter circuit is configured to be in a transmission halt state when a transmission power of the second transmitter circuit, decreased by a predetermined value, is less than or equal to a threshold,
- wherein the second transmitter circuit comprises a first switch configured to selectively connect the second transmitter circuit to an antenna, and to selectively disconnect the second transmitter circuit from the antenna, and
- wherein the second transmitter circuit is configured to be in the transmission halt state when the first switch is in an OFF state.
A communication circuit comprising:
- a first transmitter circuit;
- and
- a second transmitter circuit configured to transmit a signal simultaneously with the first transmitter circuit,
