It outputs sine waves from 2.2 GHz to 4.4 GHz and square waves from 35 MHz to 2.2 GHz, and is equipped with an SMA female connector.It comes standard with a 25 MHz high-precision crystal oscillator, controlled via a three-wire SPI interface, and supports spot, sweep, and frequency-hopping modes. The product supports 3.3 V/5 V power supplies, making it an ideal tool for RF engineering R&D and testing.Product Specifications:Output Frequency Range: ADF4351: 35 MHz–4,400 MHz (4.4 GHz)Output Signal: 2200M–4400M fundamental (sine wave); 35M–2200M fundamental submultiplies (square wave)Output Signal Interface: SMA female connectorDefault: ±50 ppm, 25M imported active crystal oscillatorCircuit diagrams and STM32 test programs are provided.Control Method: 3-wire SPI, with control pins and lock status pin exposed. Supports all functions, including fixed-frequency, frequency sweeping, and frequency hopping. Step size can be as small as 1K; at low frequencies, it can be as small as 0.1K, depending on the crystal frequency.Notes:1. Can be powered via the 3.3V pin; the power supply must provide a current of at least 500mA.2. Typical operating voltage is 5V.Package Contents:35M–4400M RF Signal Generator Module × 1
