FM TRANSMITTER DESIGN
There is a proverb:
"A person can do any work based on two principles—
-
Self-interest in the subject,
-
Fear."
For me, this project was never driven by fear. I had a genuine interest in the subject. I first heard about this fascinating instrument when I was around 14 years old, and since childhood, I’ve always been an inventive and curious kind of person.
I even tried to build this transmitter back in 12th grade, but at that time, I didn’t have enough knowledge about electronic circuits or the components involved in such designs.
Later, when I entered engineering, I chose the Electronics and Communication branch—following my passion. Now, in my third year, I’ve successfully built this project.
Before starting, many of my friends told me that it would be a very difficult project, but I didn’t back down. I began working on it as per my schedule, and after spending months in research and development, I successfully designed the transmitter circuit.
After studying all the components and doing the necessary calculations, I designed the layout on a Printed Circuit Board (PCB). The first time, I didn’t get any output or signal, but after further modifications and rework, I finally succeeded.
This FM transmitter circuit can transmit frequencies in the range of 87.5 MHz to 108 MHz, and its transmission range is approximately 500 meters.
This is first blog from me.....
