Nerlos was established with the aim of providing creative solutions in the field
of RF up to the millimeter waves. Solutions that will provide quality benefits for
components and subsystems in terms of cost, weight, electrical performance, size and overall volume.
The company was founded in 2010, and provides consulting, design, development and production services for solutions in the field of microwave, RF and ROF (radio over fiber).

What To Expect From
My Program
Unlock the future of communication with the Active Multiplexer Unit (AMU), a groundbreaking innovation designed to transform both military and civilian communication infrastructures. By enhancing the range and quality of communication systems, the AMU significantly reduces transmission and reception losses while simplifying system architecture. Most notably, it dramatically lowers the number of antennas required, maintaining the same high performance and channel capacity while minimizing the need for additional subsystems like antenna bases and cables.
Cavity resonators are typically closed electrically conducting structures (e.g., metal box) that reinforce standing-wave in the cavity filled with air/gas, or another dielectric/diamagnetic material, and configured to trap electromagnetic waves there inside.
Radio frequency and microwave cavity resonators are specifically designed to confine electromagnetic fields in the radiofrequency and microwave ranges of the spectrum.

Mr. Nimrod Rospsha is the Founder and Chief Executive Officer of Nerlos, established with the vision of redefining communications through breakthrough RF and Microwave technologies. He is the company’s lead innovator of breakthrough technologies, he drives the company’s strategy and partnerships, positioning Nerlos as a trusted partner delivering simplicity, reliability, and performance in mission‑critical environments.
Under his leadership, Nerlos has pioneered advanced RF solutions, including lightweight, PCB‑based radio cavities and duplexers (RCMP), enhanced with RF‑over‑fiber integration. These compact, high‑performance systems reduce infrastructure complexity while improving reliability for defense and security forces worldwide. Mr. Rospsha is widely regarded as an expert in translating deep technical innovation into scalable products that address pressing operational needs.
Before founding Nerlos, Mr. Rospsha accumulated more than two decades of experience across medical technology, wireless infrastructure and defense systems. At Topspin Medical he contributed to MRI‑based catheter development; at Mobile Access as RF manager, he oversaw the development of DAS for GE Healthcare; and as CEO of Flamingo Electronics, he led the creation of advanced printing MEMS products. He later spent seven years at CELLO as VP of R&D developing distributed antenna systems including the utilisation of network management solutions deployed in 13 countries, including critical public‑safety systems in the Carmel Tunnels and Ben Gurion Airport. He subsequently advanced RF innovations at Insertech, Intaltech, UV Tech, Humavox, GMedical, and Telematics, spanning airborne radar & communication, wireless charging, vital‑sign wearables, smart urban infrastructure and triangulation system.
Throughout his career, he has partnered with leading defense companies such as Elbit, Rafael, and Elta on SIGINT, antennas, chirp radar, and advanced RF components. This multidisciplinary foundation directly informs Nerlos’ ability to deliver cutting‑edge solutions for defense and HLS markets.
Mr. Rospsha holds patents on Nerlos’ flagship AMU and RCMP technologies and has been published in the Journal of Computational Physics. He is recognized for his forward‑looking perspectives on RF and communication, frequently sharing insights through defense forums and industry conferences.
Mr. Rospsha holds a B.Sc. and M.Sc. with honors in Physical Electronics Engineering from Tel Aviv University and is currently pursuing a Ph.D. in the field, focusing on stimulated super‑radiance emission in free electron lasers. His academic journey includes consistent Dean’s List recognition, a DSPG award, Intel’s Excellence Award, and a thesis prize for his research on Closed‑form FDTD‑compatible Green’s functions in which he has invented the Rospsha Triangles. These achievements reflect both his technical depth and his commitment to advancing the field of RF & communications.
