3. Step size as low as 0.1 kHz; stable at ±50 ppm with a 25 MHz crystal oscillator.
4. Supports 5V/3.3V 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 broadband RF signal generator featuring the ADF4351 chip at its core, 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 equipped with an SMA female connector.
It comes standard with a 25MHz high-precision crystal oscillator, controlled via a three-wire SPI interface, and supports spot, sweep, and hopping modes. The product supports 3.3V/5V power supply and is an ideal tool for RF engineering R&D and testing.
Product Specifications:
Output Frequency Range: ADF4351: 35MHz–4.4GHz
Output Signal: 2200 MHz–4400 MHz fundamental (sine wave); 35 MHz–2200 MHz fundamental sub-multiplies (square wave)
Output Signal Interface: SMA female connector
Default ±50 ppm 25 MHz imported active crystal oscillator
Circuit diagrams and STM32 test programs provided.
Control Method: 3-wire SPI, with control pins and lock status pin exposed. Supports all functions, including spot frequency, frequency sweep, and frequency hopping. Step size can be as small as 1 kHz; at low frequencies, it can be as small as 0.1 kHz, 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.
