    My job is to design functional and tested circuits and PCBs for your application or consult you, so you can do that your self. Just give me requirements for your circuit: the price for bill of materials, deadline and a list of required features. After prototype of device is designed I almost always advise I will order a few sample PCBs for testing. After testing and debugging is completed, I will ship them to you, so you can verify my testing results. This costs a bit extra for you, but you are buying 100% working circuit design which needs no testing. Just take it and use it in your project. If you want to know how a circuit works I can develop complete math model of the circuit. This approach is way more accurate than SPICE simulation and allows you to understand how the circuit operates. I have completed at least one project having fallowing sub circuits: Analog: Low noise, low speed front-ends (from Hz to 100KHz): Photodiode, strain gauge, pressure sensitive resistors, magnetic angle sensors, tensile, thermocouples and other. High order active filters Voltage measurement (uV to kV) Current measurement (pA to tens of A) Resistance measurements (mOhm to Mohm) Frequency measurement (below GHz) Current output Oscillators (Bubba, Pierce, Hartley, phase shift, relaxation, crystal, RC) Integrated RF transmitters/receivers Digital: PCIe USB HDMI I2S SPI High speed parallel interfaces Logic circuits (TTL, CMOS) SOCs Power: DC/DC converters: Buck, Boost, SEPIC, full bridge, Cuk, Linear AC/DC converters (up to 1.8kW) Brushless and brushed motor drivers TEC drivers CAD packages: DipTrace KiCad Altium I have fallowing equipment: 1x Osciloscope RTB2004 4 channel 10 bit 300MHz with logic analyzer having 16 differential channels up to 600Mbps. 1x Oscilloscope HMO1002 2 channel 8 bit 50MHz. 1x Multimeter HMC8012 5,75digit 1x Electronic load IT8616 1.8kVA 420VAC 20AC (60A peak) or 600VDC 20ADC with AC signal analysis 1x Electronic load IT8512C 120VDC 60ADC 1x Signal generator Rohde and Schwarz AFG 20MHz 1x TP3020 30V 20A linear power supply 1x HY5003-2 dual channel 50V 3A linear power supply 2x PeakTech 6080A 15V 3A power supply 1x VP-2000VA - 2kVA 230VAC to 120VAC converter. 1x DER-EE DE-5000 RLC meter I also have programmer for: Texas Instruments CC series, Texas Instruments MSP430 programmer, Microchip ICD3/PicKit2/AVR ISP USBasp, Segger ARM programmer, SiliconLabs 8051 core programmer

    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.

    First and foremost, I know my hourly rate is high, but being an extremely quick problem solver, I will spend fewer hours finishing your project compared to an average freelancer, while making sure that quality is at the highest level. Please DON'T consider hiring me if: - you are looking for a beginner/mediocre developer that will do the job for you as cheaply as possible - you don't want to discuss and answer questions, share a wider context about your project. I want to provide my services as I was your business partner. - my work doesn't create more value for you than your investment in my work.

    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. In this process, a procurement process for various elements, including RF elements, and a production and testing process for components have been established. Regardless of the type of product or the quantity, there is rich experience in overseas direct delivery. And, I can process various sourcing and delivery of various electronic components.
