Latest Patents

One of his latest patents is the "Wideband Microwave Detector." This invention includes a first local oscillator that outputs a first local oscillation output containing a basic wave component, a secondary high harmonic component, and a tertiary high harmonic component, which is swept within a predetermined frequency range. The device features a first mixer that performs frequency mixing of the first local oscillation output and an antenna input, outputting a first mixing output. Additionally, it includes a second local oscillator and a second mixer that generates a second mixing output. A single frequency discriminator detects a specific frequency in the discrimination input, and a mode selector switch alternates between a single super heterodyne reception mode and a double super heterodyne reception mode, synchronized with the sweep operation of the first local oscillator.

Another significant patent is the "Structure of Multi-Band Microwave Detector." This invention comprises a one-side opened hollow member with a first and second portion, along with a printed circuit board. The metal layer on the printed circuit board cooperates with the hollow member to form a horn antenna and an oscillation cavity for housing the first local oscillator. The design includes a throat portion that communicates with the oscillation cavity, a first mixing circuit, and an intermediate frequency processing circuit that features a first intermediate frequency filter, a second mixing circuit, and a second local oscillator.
