Title: Masakazu Nishida: Innovator in Amplifier Technology
Introduction
Masakazu Nishida is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of amplifier technology, holding a total of 7 patents. His innovative designs have advanced the capabilities of electronic devices, particularly in signal processing.
Latest Patents
Nishida's latest patents include a feedforward amplifier and a balanced modulator. The feedforward amplifier features a simplified circuit configuration that effectively prevents leakage signals between output terminals of a pilot oscillator and input terminals of a detector circuit. This design removes distorted signals with almost ideal improvement. Each output change-over section of the pilot oscillator and input change-over section of the detector includes a multistage change-over switch or an isolator, allowing for shared functionality between a distortion detecting loop and a distortion removing loop.
The balanced modulator, on the other hand, incorporates a pair of diodes and a plurality of line patterns, including a balance-to-unbalance converter. These line patterns extend toward and connect to the diodes, with at least a set of capacitive stubs positioned near the lines and spaced apart by a distance of .lambda./8, where .lambda. represents the wavelength at the frequency used. The capacitive stubs can be connected to the lines by bonding wires for isolation adjustments.
