Features: The core chip adopts ADF4351 according to official principles, optimizes the layout, and has extremely high power flatness within the working frequency band of the entire module. Made of high quality material,durable. Refer to the ADI official evaluation board line and layout Notice: Actual color may be slightly different from the image due to different monitor and light effect Please allow 1-3cm deviation due to manual measurement Output frequency range: ADF4351: 35M-4400M (4.4G) Output signal: 2200M-4400M fundamental wave (sine wave) 35M-2200M fundamental wave frequency division (square wave) Output signal interface: SMA female Control mode: three-wire SPI. Leads out the control pin and the lock status pin. All functions can be realized, including dot frequency, frequency sweep and frequency hopping, the step can reach 1K, the low frequency step can reach 0.1K, according to the crystal Frequency to decide.
