    For the past 20 years, I have been engaged in the design and production of electronic devices, including wireless devices. During this period, I started with antenna design, designing and producing FMCW radar in each frequency band (including millimeter waves), and continued until the signal processing unit section. In addition, a wireless direction finding system with high measurement accuracy was developed based on phase interference correlation processing method, and a coordinate measurement system combining TDOA and GPSDO was developed. The operating frequency bands of these two systems are between 20 MHz and 6 GHz. In addition, he also developed a radar frequency band signal analysis and directional analysis system based on IFM and BM methods. The frequency range of this system is 2 to 18 GHz. Moreover, while developing wireless navigation devices that can perform GPS RTK and Heading, a precision inertial navigation system has also been completed. This heading is based on a GPS system and is not affected by surrounding algae. Moreover, with the advancement of high-speed PCB design for RF systems, high-speed signal processing circuits above 1GHz and various Android, Linux devices, etc. have been widely introduced into a field. The programs used in these processes include: - RF simulation and design program: CST Studio, ADS - PCB design program: Altium Designer. - Mechanical design program: Solidworks. - Signal processing programs: ISE, Quartus, Keil, MPLAB X, Arduino. Matlab, And developed intelligent lock with facial recognition and fingerprint recognition functions, and has sufficient experience in mass production, establishing a monthly production process of more than 10000.

    A multi-disciplinary inventor and designer with expertise in quartz crystal and SAW technology, materials science, electronic design, antennas and RF, RFID, embedded firmware and hardware design, and much more. I am a creative and innovative problem solver who is equally comfortable with the big picture or working out the small details in an ongoing project. More recently I have been working with BLDC controllers up to 48V/600W and with charge controller layouts. In December 2021 I retired from IntelliSAW and began only consulting. I am seeking projects between tens of hours and 100 hours or so in scope with availability about 24 hours a week. I have been Florida-based for the past five years, but since July 2021, I am working remote in Belize. This relocation will impact shipping for any hardware support but will not affect my ability to perform design work or design reviews.
