ADF5355 high frequency signal source color screen module V3

i. Module features:

1. The ADF5355 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:A +, A- output: 250M-6.8G,B output (double frequency output of A):6.8G-13.6G;A the frequency resolution of the output terminal is 10Khz;

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. Electric mode: 6-9V/1A power above 5W;

2. Mention: schematic diagram (PDF),do not mention the source program, provide the underlying driver of ADF5355 based on STM32, and other information;

v. Chip introduction:

when the ADF5355 is used in combination with the external loop filter and the external reference frequency, it can realize the frequency synthesizer of decimal N frequency division or integer N frequency division phase locked loop (PLL). The microwave broadband VCO design allows an operating frequency of 6.8 GHz to 13.6 GHz at a radio frequency (RF) output. A series of frequency dividers output at other frequencies can achieve operating frequencies from 54 MHz to 6,800 MHz.

The ADF5355 has an integrated VCO with a basewave output frequency ranging from 3400 MHz to 6800 MHz. In addition, VCO frequencies can be divided by 1, 2, 4, 8, 16, 32 or 64, so users can generate RF output frequencies as low as 54 MHz. For applications requiring isolation, the RF output stage can be muted. The mute function can be controlled either by pins or by software.

All on-chip registers are controlled by a simple three-wire interface. The ADF5355 operates with an analog and digital power supply of 3.15V to 3.45V, with a charge pump of 4.75V to 5.25V and A VCO power supply. In addition, the ADF5355 also has built-in hardware and software power saving modes.
