  • Publication number: 20210105030
    Abstract: A feed line connects an RFIC and a radiating element. A baseband ground plane (BB ground) is connected to a ground terminal of a BBIC. A radio frequency ground plane (RF ground) is placed in such a manner as to overlap the BB ground. The RF ground serves as a return path of the feed line. A first inter-ground connection circuit connects the BB ground and the RF ground. Furthermore, a second inter-ground connection circuit connects the BB ground and the RF ground. Connecting parts between these grounds and the second inter-ground connection circuit are arranged closer to the edges of these grounds than connecting parts between these grounds and the first inter-ground connection circuit. The connecting part between the ground and the second inter-ground connection circuit is placed on one side of a certain imaginary straight line that passes substantially the geometric center of the ground.

  • Patent number: 10972051
    Abstract: A power amplifier circuit includes a first amplifier that amplifies an input signal and outputs an output signal; a second amplifier that, in accordance with a control signal, amplifies a signal corresponding to the input signal, generates a signal having an opposite phase to that of the output signal, and adds the signal to the output signal; and a control circuit that supplies the control signal to the second amplifier. The control circuit outputs the control signal so that during operation of the power amplifier circuit in a first power mode, a gain of the second amplifier is not less than zero and less than a predetermined level and during operation in a second power mode lower than the first power mode in output power level, a gain of the second amplifier is not less than the predetermined level and less than a gain of the first amplifier.

  • Patent number: 10965325
    Abstract: A communication unit includes the following elements. A first transmit circuit outputs a first signal or a second signal from a first input signal. A first amplifier amplifies the first signal and outputs a first amplified signal. A first signal generating circuit generates a third signal having a frequency higher than a frequency of the second signal, based on the second signal and a first reference signal. A first filter circuit receives the third signal and allows one of a frequency component representing a sum of the frequency of the second signal and a frequency of the first reference signal and a frequency component representing a difference therebetween to pass through the first filter circuit and attenuates the other one of the frequency components. A second amplifier amplifies the third signal output from the first filter circuit and outputs a second amplified signal.

  • Publication number: 20210075920
    Abstract: A maintenance support device includes a memory that stores work result information that corresponds to a maintenance work that has been performed to solve a failure of an image processing apparatus. A processor is configured to acquire, and store in the memory, first work result information corresponding to a first maintenance work performed to solve a first failure type. After the first work result has been stored, the processor acquires, and stores in the memory, second work result information corresponding to a second maintenance work performed to solve a second failure type. It is then determined whether the first failure type matches the second failure type. Upon determining that the first and second failure types match, the first work result information is then updated to indicate that the first maintenance work has not been successful.
