Title: Kenji Nasu: Innovator in RF Technology
Introduction
Kenji Nasu is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of radio frequency (RF) technology. With a total of 2 patents, Nasu has developed innovative solutions that address critical challenges in RF signal processing.
Latest Patents
Nasu's latest patents include a Wilkinson-type combiner and an RF generator. The Wilkinson-type combiner is designed to be low-cost and compact, effectively suppressing the risk of damaging an isolation resistor due to combination loss. This device features first and second input terminals for RF signals, an output terminal, and a wiring line that combines the RF signals. Additionally, it includes an isolation unit formed by a series of resistors and a transformer, along with a detection circuit to monitor current flow. If the current exceeds a prescribed value, a determination circuit blocks RF signal input to prevent damage.
The RF generator developed by Nasu includes a modulation circuit that outputs a pulsed RF signal. It also features a variable attenuation circuit to adjust the signal level and an output power detecting unit. Two comparative arithmetic circuits control the level of the pulsed RF signal based on detected voltage values. A switching circuit allows for dynamic adjustments based on timing settings.
