SDRtekniker

SDRtekniker, or software-defined radio technician, is a professional who works with software-defined radio technologies to design, implement, test, and maintain radio communication systems in which most signal processing tasks are performed in software on general-purpose processors or DSPs rather than in dedicated hardware. SDRs enable flexible modulation schemes, spectrum management, and rapid prototyping of new protocols.

Typical responsibilities include selecting appropriate SDR hardware (for example USRP, HackRF, bladeRF, RTL-SDR), developing and optimizing digital signal processing algorithms for modulation, filtering, coding, synchronization, and waveform generation, and implementing them using toolchains such as GNU Radio, MATLAB/Simulink, or custom C++/Python software. SDRtekniker perform system integration, calibration, performance testing, and spectrum analysis, as well as troubleshooting, documentation, and ensuring compliance with relevant standards and regulations.

Required skills and qualifications usually include a degree in electrical engineering, telecommunications, computer engineering, or a related field. Strong foundations in RF concepts (frequency planning, antennas, LNA, mixers, ADC/DAC sampling), digital signal processing, and programming are essential. Experience with SDR platforms, FPGA programming, and embedded systems is common, along with familiarity with hardware testing equipment and version control.

Work environments vary from telecommunications operators and research labs to defense contractors and hobbyist communities. SDRtekniker collaborate with RF engineers, software developers, and hardware technicians to deliver flexible radio solutions for wireless communication, spectrum monitoring, and experimental research.
