Introduction

Juan Rivera is an accomplished inventor based in Torrance, California. He has made significant contributions to the field of technology, particularly in the area of signal processing and antenna design. With a total of two patents to his name, Rivera's work showcases his expertise and innovative spirit.

Latest Patents

One of Rivera's latest patents is the "Multi-octave differential upconverter." This apparatus includes a differential amplifier and a differential mixer. The differential amplifier is designed to receive a multi-octave differential input signal and produce an amplified multi-octave differential output signal. It effectively reduces second-order harmonic distortion through common mode rejection. The differential mixer then multiplies the amplified output signal with a local oscillator input signal, resulting in an up-converted sub-octave differential output signal. Notably, both the multi-octave differential input signal and the up-converted output signal share a similar bandwidth.

Another significant patent is for "Millimeter wave phased array systems with ring slot radiator element." This invention features a phased array antenna structure that operates at millimeter-wave frequencies, incorporating multiple ring slot radiator elements. The RF feed structure for each radiator element includes a feed via that extends partway through a multi-layer structure. A strip line feed probe extends from the via toward the radiator element. A key aspect of this design is the inclusion of multiple mode suppressors surrounding the via, which facilitate a smooth transition from coaxial to strip line RF transmission modes. The feed probe is tailored to provide either narrow-band or wideband frequency characteristics.
