Building & Understanding RF – Tx + Rx

[Adeel]

Hello,

 

I m trying to studying RF but i m not getting much help from the internet. can anyone help me teach me about following things below:

 

 1 . How to build RF (Tx + Rx)

 2 . How to Calculate the Mhz range

 3 . What is the role of L1 number of turns of a simple coper wire

 4 . if you can help me to build very very simple RF (Tx + Rx) to on/off the LED with each calucation then maybe i can understand better.

 

I m dying to learn this, please help me.

 

Thank you

Hi Adeel,

To make an RF you would need an RF oscillator, and you can search for LC oscillator equations which will give you an idea how the value of L and C are related to the frequency.

Then you need an antenna to transmit/receive the RF, and there are equation relating the antenna lenght and the frequency need to be transmitted/received.

 

There are so many RF transmitter/receiver modules available which can make your job easier!
