Title: Larry Y Onotera: Innovator in Microwave Radio Testing

Introduction

Larry Y Onotera is a notable inventor based in Surrey, Canada. He has made significant contributions to the field of microwave radio technology, holding a total of 3 patents. His work focuses on enhancing the testing and performance of radio systems.

Latest Patents

One of Larry's latest patents is an "Apparatus for testing microwave radios having 35 MHz." This invention involves a method where a 70 MHz sinusoidal test signal is down-converted and shaped to create a 35 MHz test signal for radio sets. The output from the radio set is then processed through an up converter, ensuring that amplitude information is preserved while doubling the frequency. This innovative approach allows for accurate measurement of radio characteristics as if a 70 MHz intermediate frequency (IF) were used instead of a 35 MHz IF.

Another significant patent is the "Built-in linearity testing arrangement for an FM radio system." This invention connects the baseband input of a frequency modulation radio transmitter to a square wave generator. The system adjusts the amplitude of the square wave to achieve a predetermined deviation in the FM transmitter. The output frequency of a pilot oscillator is also applied to the baseband input, where it undergoes amplitude modulation due to system non-linearities. The resulting signal is processed to measure the system's non-linearity, providing valuable insights into performance.
