Module description:
The ADF4351-OLED is used in combination 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 the key operation can realize the functions of point frequency and frequency sweep.
(5) The distributed code does not include the USB port program, does not provide a microcontroller tutorial, and additional functions such as communication with the host computer need to be developed by themselves.
(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.
