Size comparison of Windfreak technologies SunthHD Mini vs Zippo lighter - RF Cafe

When Windfreak owner/engineer David Goins told me his new SynthHD Mini was about the size of a Zippo lighter, I decided to check out his claim. Click the thumbnail above to see just how right he is!

Port Richey, Florida, April 14, 2021 – Windfreak Technologies announces the availability of the new SynthHD Mini RF Signal Generator. The SynthHD Mini is the smallest 10 MHz to 15 GHz RF Signal Generator in the world - a mere 1.60 x 1.60 x 0.48 inches (4.06 x 4.06 x 1.22 cm). Expect excellent performance despite the ultra-small size and price of this device.

Tune any frequency between 10 MHz and 15 GHz in 0.01 Hz resolution. Adjust calibrated amplitude in 0.01 dB resolution up to +20 dBm and across more than 30 dB of range. Perform FM, AM, Pulse, Sweep, and List Modulations.

Windfreak Technologies has set the bar on microwave radio frequency generators for quality, size, and price. As always, our products are designed and manufactured in the USA!

In Stock. Ships within 5 days.
