Title: Akio Funae: Innovator in Radar Technology
Introduction
Akio Funae is a prominent inventor based in Nishinomiya, Japan. He has made significant contributions to the field of radar technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and functionality of radar receivers and devices.
Latest Patents
Funae's latest patents include a radar receiver and a radar device equipped with the same. The radar receiver is designed to effectively prevent local oscillator signals from leaking out from an antenna. It comprises a local oscillator, a mixer, a buffer amplifier, and a mode switcher. The local oscillator outputs a local oscillation signal (LO), while the mixer combines a high-frequency signal (RF) received by a radar antenna with the local oscillation signal. The buffer amplifier is strategically placed between the local oscillator and the mixer. The mode switcher allows for operation in at least two modes: a standby mode, where power is supplied to the local oscillator but not to the buffer amplifier, and a reception mode, where power is supplied to both components.
Another notable patent is a microwave frequency converter for a radar receiver. This invention prevents the frequency of the local oscillator from interfering with the oscillation frequency of a magnetron included in the radar receiver. It allows for the reception of signals from considerably short distances. The voltage of an RF amplifier connected to the microwave frequency converter is synchronized with the oscillation output of the magnetron. The gate and drain voltages of a FET used in the RF amplifier are switched OFF during specific times to enhance the performance of the microwave frequency converter.
