Chris Nadovich is a senior systems architect, developer, and engineering project team leader with diverse experience and a track record of success. He will consider any opportunity to undertake complex engineering efforts with an emphasis on RF, Microwave, Analog, and Digital signal processing, board level design, EMI/EMC testing, and automated instrumentation.

Nadovich's areas of expertise are:


Nadovich received BSEE and MEEE degrees from Rensselaer Polytechnic Institute in 1981 with specialty in network theory and finite element analysis.

Mr Nadovich has worked in industry for over 20 years, serving as lead engineer guiding ground-up development of a number of sophisticated signal processing systems, including Software Radios, SuperResolution Direction Finding systems, Microwave and RF Measurement systems, and specialized Monopulse and SAR radars. This work gave him extensive experience in both hardware and software, including RF/Analog design, signal processing, test, and measurement from DC to 200 THz, and real time DSP using high performance digital systems and embedded software. In addition to being a skilled RF, microwave, and board-level electronics developer with a fresh skill-set on state of the art tools, Nadovich is also an experienced engineering team leader and project engineer, having worked in various supervisory roles, coordinating the work of individuals and subcontractors.

While working in industry as an engineer in the late 1980's and early 1990's, Nadovich was also a competitive bicycle racer. In 1994, Nadovich, united his skills as an engineer with his love for bicycle racing when in he designed the velodrome for the 1996 Olympic Games. The 250 meter track has 42 degree banking in the curves and a proprietary shape designed by Nadovich using a hybrid symbolic/numerical model implemented in Mathematica and based on the theory of the Fresnel integral. The track was temporarily installed at the Stone Mountain Cycling and Archery Venue near Atlanta Georgia for use in the 1996 Olympic games. To date, Nadovich has been the designer of over a dozen velodromes worldwide. He continues to be an active cyclist and has recently (2011) completed the 1240 km Paris Brest Paris randonnée.

Instruments Book By Nadovich Reflectometry Calculator for Android Since then Nadovich has continued his work in DSP, RF, and Microwave engineering as an independent consultant, along with several Internet and Software related projects in conjuction with the ISP, JTAN.COM. These projects include contributions to the open source community and the development of technically related cell phone applications. Nadovich has written a book to help advance the state of the art in software-defined automated instrumentation. The book: Synthetic Instruments, Concepts and Applications was published by Elsevier in 2004.

These days, along with his consulting on RF/Microwave design, FCC compliance testing, DSP, and Board Level layout and design, Nadovich is Director of Laboratories at Lafayette College in Easton, PA. His main responsibility is managing teams of young engineers engaged in multidisciplinary capstone projects ('10, '11, '12, '13, '14, '15).


Nadovich has decades of experience with cutting edge hardware development. He has designed and integrated modern RF and analog components in surface mount, stripline, coaxial, and waveguide assemblies, working at frequencies from DC to 94 GHz and power levels from thermal noise to 10 kilowatt CW. He has used RF/Analog EDA and Simulation tools including PSPICE, COMSOL Multiphysics, CST Microwave Studio, Sonnet, and Eagleware. Nadovich has developed several radar systems, including monopulse trackers, active phased arrays, and SAR imaging systems, and high-speed analog control systems for adaptive antennas and interference cancelers. Most recently he has been working on a high speed automated test system in a tablet form-factor, including detailed design of an ultra-compact microwave receiver and exciter.


Instrumentation Radar HF Receiver Array Nadovich, an expert up/downconverter designer, was one of the first engineers in the world to create a detailed design for a Software Defined Radio. He is particularly experienced in real-time DSP multiprocessing, having designed two significant multiprocessor DSP systems: one, a radar control system comprising over 15000 lines of C code executing on three Intel X86 processors, the other a Software Radio array with forty-nine TMS-320 processors in concurrent operation. More recently Nadovich has designed FPGA based packet modems, synthetic test and measurement systems, and other software radia and DSP intensive systems.

These high performance digital systems had extensive Digital Signal Processing (DSP) and Software Defined Radio (SDR) capabilities, including FIR and IIR digital filters, FFT and Wavelet transforms, decimation, interpolation, and multidimensional signal processing algorithms.
