Title: Steven Mittleman and the Ring Hybrid Mixer
Introduction
Steven Mittleman is an inventor associated with Framingham, Massachusetts. His patent work includes a ring hybrid mixer, a microwave circuit designed to combine and separate signals.
Latest Patents
Mittleman is credited with 1 patent, titled “Ring Hybrid Mixing.” The invention describes a hybrid ring mixer built on a gallium arsenide substrate. An annular conducting ring forms part of a strip transmission line, with outward-facing conductors serving as local oscillator, signal input, and intermediate-frequency ports. Inward-facing conductors connect to mesa diodes, while a grounded conducting surface and a plated via provide an electrical connection through the substrate.
The patent also details a fabrication process involving epitaxial layers, diode contacts, circuit metallization, an etched via, and backside plating. These features support the mixer’s electrical layout and its integration on the substrate.
Career Highlights
Mittleman’s documented patent contribution focuses on microwave and semiconductor circuit design. The ring hybrid mixer combines a carefully arranged port structure with diode connections and a grounded substrate surface.
Collaborations
Mittleman is associated with Alpha Industries. His listed coworkers include Ian Crossley and Daniel Donoghue.
Conclusion
Steven Mittleman’s patent record highlights a specialized contribution to microwave engineering through the design and fabrication of a gallium arsenide ring hybrid mixer.
