Radio Frequency Engineer

Designs and tunes the satellite's RF communication chain (filters, low-noise amplifiers, power amplifiers), creates radio-board schematics/layout for high-frequency design, and tests components with a VSWR/spectrum/network analyzer. Suited to students with a solid physics/RF background; SDR or HAM radio experience is useful. Unpaid, 8-10 hours/week, primarily remote with occasional work at Tartu Observatory.
