Simple Stereo FM Transmitter Circuit

Last Updated on September 22, 2021 by Admin Leave a Comment

A superb stereo FM transmitter circuit is indicated here.

The circuit is in light of the IC BA1404 from ROHM Semiconductors.

BA1404 is a solid FM stereo modulator that has assembled in stereo modulator, FM modulator, RF intensifier circuitries.

How the Circuit Functions

The FM modulator can be worked from 76 to 108MHz and power supply for the circuit can be anything between 1.25 to 3 volts.

In the circuit R7, C16, C14 and R6, C15, C13 frames the preemphasis system for the privilege and left channels individually.

This is finished coordinating the recurrence reaction of the FM transmitter with the FM beneficiary.

Inductor L1 and capacitor C5 is utilized to situated the oscillator recurrence. System C9,C10, R4,R5 enhances the channel detachment.

38kHz gem X1 is joined between pins 5 and 6 of the IC.

Composite stereo sign is made by the stereo modulator circuit utilizing the 38kHz quartz controlled recurrence.

Notes.

Assemble the circuit on a decent quality PCB.

Powering the circuit from a battery will decrease interference.

Utilize a 80 cm copper wire as reception antenna.

For L1 make 3 turns of 0.5 mm dia enameled copper wire on a 5mm diameter ferrite center.

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!
