A general-purpose digital RF module based on the SDR architecture, integrating a digital source and a power amplifier unit. The FPGA in the digital source generates drone jamming signals using various digital modulation schemes, which are converted into RF signals via the SDR platform and amplified before output. The digital source supports a frequency range of 100MHz to 6000MHz with a configurable bandwidth of up to 200MHz. It automatically generates jamming codes tailored to drone types, supporting common protocols such as ELRS, Crossfire, Flysky, OcuSync, LightBridge, and SyncLeas. Featuring a modular, compact, and flexible design, it is easy to integrate.
