ADF4350/ADF4351 color display module V3

i. Module features:

1. The ADF4350/ADF4531 module is made by senior engineers with full reference to the design of the version; The PCB has beautiful appearance, reasonable layout and design, and exquisite materials;

2. V3 is a significantly upgraded version of the previous version, mainly including:

a, in order to improve the output signal quality, greatly optimize the circuit;

b. The display screen is upgraded from 2.8 inches to 3.5 inches, and the Resistance touch is upgraded to capacitive touch. Added user experience;

c. The control function of PC software is added, and PC software can control module output through TTL serial port;

3.output frequency range :138M-4.4G(ADF4350),35M-4.4G(ADF4351);

4. The module can realize the following functions:point frequency, single sweep frequency, interval sweep frequency, continuous sweep frequency, output switch and control output power (+5, +2, -1,-4, Special note: these four numbers only represent four gears, non-designed output power values)。

5. There are three modes of module operation:a、 touch screen operation; B, PC software control; 3, button operation;

6.key function: 1. FSK (the fastest signal is 10mS);2. Switch RF output; 3. Frequency sweep; 4. Stop frequency sweep;

7. The interface of PC software (see the above figure) is similar to that on the display screen, so the operation is basically the same, and the operation on PC will be displayed synchronously on the display screen;

8. The module can not only maintain the set parameters, but also maintain functional operations. For example, if the frequency sweep operation is maintained, the module will perform frequency sweep with the maintained parameters next time it is powered on.

9. Power mode: 5V power, USB power can be directly used;note that for higher requirements, it is recommended to use 5V power supply with low ripple, and the power of the power supply is greater than 5W (I .e. above 5V1A);

v. Chip introduction:

when the ADF4350/ADF4351 is used in combination with the external loop filter and the external reference frequency, it can realize the fractional N division or integer N Division phase locked loop (PLL) frequency synthesizer.

The ADF4350/ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 2200 MHz to 4400 MHz. In addition, using a 1/2/4/8/16 frequency division circuit, users can generate RF output frequencies as low as 35Mhz/137.5 MHz. For applications requiring isolation, the RF output stage can be muted. The mute function can be controlled either by pins or by software. At the same time, the auxiliary RF output is provided and can be turned off when not in use.
