Latest Patents

Yoshiaki's latest patents include an array antenna apparatus and a microwave transceiver module. In his transceiver module, a microwave analog signal interface is provided between the transceiver module and an antenna element. All signal interfaces, except for the power supply, are digital signal interfaces, configured as one chip on a semiconductor. An internal reference signal generates a local signal serving as a reference by multiplying a high-frequency digital clock signal supplied from the outside. Simultaneously, it generates a reference signal capable of synchronous operation by a lower frequency digital clock signal supplied from the outside in the clock generator. The frequency of the generated reference local signal can be varied by controlling the inner multiplication number or the frequency of the higher frequency digital clock signal supplied from the outside. Additionally, both transmission and reception can be executed with an arbitrary frequency by varying the frequency of the transmission waveform generator.

Another notable patent is for a nonreciprocal device. According to one embodiment, this device includes a first component portion serving as a circulator and a second component portion also serving as a circulator. The first component portion consists of a first carrier and a first Y junction-shaped line with three branch lines. The second component portion includes a second carrier plate provided on the back surface of the first carrier plate and a second Y junction-shaped line with three branch lines.
