Atek Midas, a Turkish company, has launched DSG-22.6 GHz, a high-performance, open-source RF signal generator designed to provide professional-grade frequency synthesis at a fraction of the cost of traditional benchtop equipment from manufacturers like Anritsu or Keysight. It has an operating frequency range of 0.15 GHz to 22.6 GHz and is designed for makers and production test environments for RF testing, calibration, wireless experimentation, and microwave research.
The device offers 1 Hz tuning resolution, adjustable output power −15 dBm to +20 dBm, and supports linear and logarithmic frequency sweeps with configurable start/stop frequencies, step size, and dwell time. It achieves ≥40 dBc spurious and harmonic suppression on the filtered output path and features a tuning speed of <100 µs. The generator includes a capacitive touchscreen display and can also be controlled over a USB Type-C port and/or Wi-Fi.
DSG-22.6 GHz specifications:
- Frequency range – 150 MHz to 22.6 GHz
- Tuning resolution – 1 Hz
- Output power – +20 dBm to -15 dBm, adjustable in 1 dB steps
- Filtered output
- 2 to 16 GHz – up to 10–15 dBm
- 16 to 18 GHz – up to 7–10 dBm
- Unfiltered output
- 0.15 to 20 GHz –up to 17–20 dBm
- 20 to 22.6 GHz – up to 14–18 dBm
- Filtered output
- Sweep mode – Linear and logarithmic frequency sweep with adjustable start/stop, step size, and dwell time
- Signal purity
- Spurious & Harmonic Suppression – Min 40 dBc (filtered path) up to 10 dBm output power
- Phase Noise @ 10 kHz offset – -108 dBc/Hz (at 1 GHz); -85 dBc/Hz (at 10 GHz)
- Tuning Speed – <100 μs
- Display – Built-in capacitive touchscreen
- Wireless – Wi-Fi with built-in web interface
- USB – USB Type-C port for power and SCPI command set
- Expansion – 10 MHz External reference input via SMA connector
- Misc – Built-in monitoring for temperature, voltage, current, and PLL lock status
- Power supply – 5V / 1.5A via USB Type-C port
- Dimensions – 114 x 60 x 28.2 mm (CNC-machined aluminum enclosure)
- Weight – 250 grams
The device can be controlled using SCPI commands over USB Type-C and can be directly integrated into automated test setups or laboratory measurement systems. The device also includes a Python-based user interface for remote control and scripting, as well as Wi-Fi connectivity with a built-in web interface for configuration and operation in a browser on a computer or smartphone. The company plans to release all the design files on GitHub, including firmware source code, hardware schematics, Python UI, and 3D design files, when the campaign ends and their goal is reached. At the time of writing, the 3D files, firmware, and PDF schematic are already available.
While it’s probably the first open-source hardware signal generator we’ve seen, we previously covered other open-source RF tools, such as the HackRF Pro, web-controllable uSDR, xSDR, and powerful boards like AntSDR E200, which is based on an AMD Embedded Zynq 7020 SoC.
One of the most interesting things about this device is that it utilizes Atek Midas’s own internal IC products, which the team notes helps reduce supply chain risks. Production is split between PCB manufacturing in China and final assembly, CNC machining, calibration, and testing in Turkey.
The DSG-22.6 GHz is currently listed on Crowd Supply with a $24,000 goal. The single unit is priced at $1,590 with free worldwide shipping via Mouser Electronics. Orders are expected to begin shipping in mid-August 2026. More technical details and documentation can be found on the Atek Midas website.
