Why Qubit Microwave
-
Over 40 years of combined RF/microwave engineering experience spanning antenna design, MRI systems, ultra-wideband switching, and quantum computing hardware.
-
We combine electromagnetic field theory with state-of-the-art 3D EM simulation to reduce design iterations and hit performance targets on first prototypes.
-
We design around insertion loss, isolation, return loss, and phase stability as system-level performance levers—not datasheet trivia. Small losses early in a signal chain dominate overall sensitivity.
Boutique Engineering Built for Direct Access
Qubit Microwave is a small, specialized team built for customers who value direct access to technical decision-makers. We bring PhD-level expertise and research-trained engineering discipline to every project.
Every product is benchmarked before shipment to confirm it meets agreed performance specs. All products are designed and fabricated in the United States, with 60-day warranty and 30-day money-back guarantee.
