Product Description
ADF4351 phase-locked loop signal source frequency synthesizer with microcontroller control with cavity RF PLL
ADF4351 phase-locked loop signal source frequency synthesizer with microcontroller control with cavity RF PLLHighlights:
The PLL has a cavity box, and the main control module of STM32 microcontroller is attached to the cavity box. It is beautiful and easy to use. The internal phase-locked loop (PLL) is powered by a linear regulator chip with low ripple, which can effectively control spurious signals and make the spectrum purity and frequency stability of the PLL better.

Module parameters
Module model: ADF4351-cavityModule type: broadband PLL frequency sourcePower supply voltage: DC-5VModule current: 210mA (MAX)Module communication interface: USBModule communication protocol: serial port instructionModule control mode: upper computer instructionModule reference frequency: 100MHz (default); external input clockReference frequency signal amplitude: 700mVpp(MIN)Frequency stability: greater than 25PPMPhase noise: different frequency phase noiseModule output frequency range: 35MHz-4.4GHzFrequency control step: 0.1MHzFrequency sweep step time: 1mS(MIN)Module output power: 7dBm (MAX); different frequency output power is differentModule output interface: SMA; 24-hour salt spray anti-oxidationModule output signal: sine wave or square waveModule output channel: 1 wayModule output impedance: 50 ohm matchingSignal characteristics of the module: 35MHZ--2.2GHz square wave (fundamental frequency division) 2.2GHZ--4.4GHz sine wave (fundamental wave)Module features: host computer USB communication port, host computer software control phase-locked loop module, the module can achieve 35MHz-4.4GHz frequency output, frequency, frequency sweep, frequency hopping and other basic functionsModule application: RF signal frequency generator, sensor excitation source, line loss attenuation detection, scanning clock signal generatorModule specifications: 61*47*13mm; length*width*height-PCB sizeModule working temperature: 0-75℃; civil gradeModule descriptionThe ADF4351 is used in conjunction with an external loop filter and external reference frequency to implement an integer-N frequency-locked loop (PLL) frequency synthesizer.The ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency range of 2200 MHz to 4400 MHz. In addition, with 1/2/4/8/16/32/64 crossover circuits, users can generate RF output frequencies as low as 35 MHz. For applications requiring isolation, the RF output stage can be muted. The mute function can be controlled by pins or software. At the same time provide auxiliary RF output, and can be turned off when not in use.
Precautions for using the module(1) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.(2) Correct power supply, reverse connection is prohibited, and the voltage should not exceed 6V.(3) It is recommended to use a good patch cord to connect the spectrum analyzer or oscilloscope to observe the output signal. Poor contact or poor quality wires may cause signal attenuation or excessive noise.(4) When the PLL module is properly powered, the frequency signal can be generated, and it has the function of power-off storage. The software of the host computer can realize the functions of frequency and frequency sweep.(5) The module only distributes high-level software and communication protocols, and does not provide codes and single-chip tutorials.(6) The phase noise, harmonics, power output and other corresponding indicators of the phase-locked loop module. The typical test parameters are included in the details.
Frequently asked questionsQ: Is the output waveform of AD4351 not a sine wave, and the harmonics are very large?A: ADF4351 is a digital phase-locked loop. The frequency output below 2.2G is divided frequency output, the output waveform is similar to square wave, if you need a sine wave, you need an external filter.Q: Can the fastest sweep speed of ADF4351 be only 1mS? Can the minimum step be only 0.1MHz?A: The current loop bandwidth design and software design on the board, in order to support 35M-4.4G frequency can be output normally, so the minimum step and the fastest sweep time are fixed, and it is necessary to pursue smaller steps and faster sweep Time will require buyers to make hardware and software adjustments.Q: What are the two lights on the board for PLL module?A: Red is the power indicator, blue is the lock indicator, and both lights are on for normal operation. If the lock light is not bright or slightly bright, you can reset the MCU until the lock light is always on, the module is normal output
