摘要： According to one embodiment, an electronic apparatus includes receiver circuitry, transmitter circuitry, and processor circuitry. The receiver circuitry receives a first signal including first data via a first frequency band. The transmitter circuitry starts transmission of a second signal via at least a part of the first frequency band. The processor circuitry reduces interference caused by the second signal to receive the first signal. The processor circuitry increases a power of the second signal until reducing the interference becomes stable for the first time since the transmitter circuitry has started transmission of the second signal.

摘要： A high-frequency circuit of embodiments includes a dielectric substrate, a signal line, a circuit element, and an array of heat conductive patterns. The signal line is formed on at least one surface of the dielectric substrate, and transmits a high-frequency signal. The circuit element is formed on the at least one surface or both surfaces of the dielectric substrate. The array of heat conductive patterns is formed on the at least one surface of the dielectric substrate. The array of heat conductive patterns can generally release heat from the dielectric substrate.
