35 MHz - 4.4 GHz RF Synthesizer ADF4351 Based Evaluation Board Electronic Project

How is the rf generator connected with the arduino and the lcd because the diagram does not show please explain because I do not understand how to connect between the pieces please help me 😓

[@1nformatica]

The connection to the RF generator are shown in green at the bottom of the screen here : kzbin.info/www/bejne/norYdKGpqtatoKM The "LCD buttons shield" plugs on top of the Arduino. You need to look at the original project linked in the video description. Thanks for watching, have a great day!

@@shba3387 The "LCD buttons shield" plugs on top of the Arduino to the header pins. See the description of the shield here: s.click.aliexpress.com/e/_ANVxsd The screen is driven by the Arduino, it has no connection to the RF generator. You need to look at the Arduino sketch.

[@MCsCreations]

Wow, that's really nice! I've already seen testers for vtxs, to check the mw power of the vtx. But something to test the antennas I've never seen! Great work, man! 😀

[@1nformatica]

Hey thanks! Wait to you see the "El Cheapo" spectrum analyser!! Hope you're OK and will put up a new video soon. Un abrazo!

[@MCsCreations]

1nformatica Great! Looking forward to see it! 😀 And I'm fine, thanks! What about you?

[@anushkatripathi8440]

The LCD displays "NOLOCK" the whole time, what could be the possible error and solutipn

[@1nformatica]

Sorry, I have not seen that problem. Googling it shows maybe you have a grounding issue with your build. Thanks for watching, have a great day!

[@bonfacemusyoka2337]

can i use the same idea on ADF3450 chip and if yes where can i get the source code? thanks

[@1nformatica]

The same idea should work. There is a link in the video description to the original project with the code linked. Also see here : github.com/JQIamo/ADF4350-arduino Thanks for watching, have a great day!

[@yadabub]

I've still got a box full of 10 base 2 coax segments, isa boards, and a hub/converter. They haven't been used for 20 years at least.

[@1nformatica]

He he! I'm not the only hoarder then! Must be space in a museum somewhere. All those happy hours chasing flaky cable faults and crawling around on the floor...happy days!

[@ovalwingnut]

GOOD TIMES. Thank you for the video. Exactly what I was curious about. Subbed! 👍😁

[@1nformatica]

Thank you! It is a very useful board to have.

[@damny0utoobe]

I subscribed to you. I hope you keep making more DIY RF projects. I'm on a journey of my own trying to get in this space.

[@1nformatica]

Hey thanks! I have a few RF projects like this kzbin.info?o=U&video_id=DSFIgjnkaf4 If you let me know what subject you would like to see covered I'll see what I can do.

[@damny0utoobe]

@@1nformatica Thanks. I watched your SDR video too. I just ordered the same parts and will replicate what you've done. BTW, that link is only viewable for you. I think you meant: kzbin.info/www/bejne/eoSpepqgo9CUnJY

[@damny0utoobe]

@1nformatica, what do you think about doing a projects for high speed ADC DAQ, RF receivers, mixers and diy test equipment.

[@1nformatica]

That's a very broad spectrum! Do you have something specific in mind, for example an piece of test gear that would be most useful to you?

[@shriram5494]

Hey Greg, I was wondering if it is possible to use the adf4351 as a VCO for plain analog FM? I wanted to make my electric guitar wireless

[@1nformatica]

I don't think this is a suitable device for that. Maybe this is a better option : DSP PLL 87-108MHz FM Transmitter Module s.click.aliexpress.com/e/_9vwBpv

[@edmanuel6885]

Does the project continue to work with the LCD Shield removed - with the last frequency loaded? Don't need to leave the LCD shield inside the finished project.

[@1nformatica]

Sorry I cannot try that due to the way I have soldered the connections. You can contact the original author here : f6kbf.free.fr/ Please consider subscribing if you have not done so already!

[@edmanuel6885]

@@1nformatica Thanks. I will, and I have ordered a SMT shield to go between the Uno and the LCD/Keys. I'll update you when I'm done.

Hello sir , thank so much for you beautiful content can i ask .Did you connect the 10Kohm resistor between CE and GND terminals ?

[@1nformatica]

Hi thanks! On my board I had to connect a 1K ohm resistor between CE and 3.3 Volts as you can see here : kzbin.info/www/bejne/norYdKGpqtatoKM Please consider subscribing if you have not done so already!

[@1nformatica]

@UCJR2cc75LY825Ef3hiWudXA I used 1K it is only a pullup resistor so either will do.

[@hatemalhrbi5731]

Hey again , i used spectrum analyzer but its not working at all i saw a frequency spike but its not moving when i change frequency from the lcd shield

[@1nformatica]

@@hatemalhrbi5731 Usual trouble shooting, double check all the wiring. Do you see the LCD display correctly? If not check the Ardunio programming. You can contact the original author here : f6kbf.free.fr/contacts.html

[@rohitmisra5430]

Would it be possible for you to provide a connection diagram between the Keypad LCD shield and the Arduino UNO? I am not able to discern the connections from the diagram provided on the project website.

[@1nformatica]

Sorry, I do not understand. The LCD shield plugs directly into the Arduino. The only connections needed are to the ADF4351 board. These just happen to be easier to do using the LCD shield pins rather than the Arduino itself.

[@rohitmisra5430]

@@1nformatica Ok! Thanks for the clarification.

[@1nformatica]

Let me know if you have any other questions.

Hi, would this be suitable for recalibrating an old hifi FM tuner?

[@1nformatica]

I guess so, I think it is accurate to within 50ppm.

[@ruhnet]

You would probably want to use a low pass filter (like 120-160MHz) if you used it for that purpose.
