Product Features:1. Supports a wide frequency range of 35 MHz to 4.4 GHz, with fundamental sine wave and subharmonic square wave outputs.2. Supports three-wire SPI control, as well as spot frequency, sweep frequency and frequency hopping modes.3. Step size as low as 0.1 K; stable at ±50 ppm with a 25 MHz crystal oscillator.4. Supports 5 V/3.3 V power supply, making it an ideal tool for RF engineering R&D and testing.5. Equipped with an SMA female connector, making it easy to integrate into other devices or systems.Product Description:The ADF4351 development board is a high-performance, wideband RF signal source, centred around the ADF4351 chip, with an output frequency range spanning 35 MHz to 4.4 GHz. It outputs sine waves from 2.2 GHz to 4.4 GHz and square waves from 35 MHz to 2.2 GHz, and is fitted with an SMA female connector.It comes with a 25 MHz high-precision crystal oscillator as standard, 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 and is an ideal tool for RF engineering research, development and testing.Product Specifications:Output Frequency Range: 35 MHz–4,400 MHzOutput Signals:2,200 MHz–4,400 MHz: Fundamental (sine wave)35 MHz–2,200 MHz: Fundamental sub-multiples (square wave)Output Signal Interface: SMA female connectorDefault: ±50 ppm, 25 MHz imported active crystal oscillatorCircuit diagrams and STM32 test programmes are provided.Control method: 3-wire SPI, with control pins and lock status pin exposed. All functions can be implemented, including fixed frequency, frequency sweep and frequency hopping; step size can be as fine as 1K, and at low frequencies as fine as 0.1K, depending on the crystal frequency.Notes:1. Power can be supplied via the 3.3V pin; the power supply must provide a current of at least 500mA2. Typical power supply voltage is 5VPackage Contents:RF signal generator module × 1
