FM amplifier is used for amplify signal from exciter in broadcast radio station. In this page, RF FM Amplifier uses solid state material with minimum gain 9dB. Input of the FM Amplifier needs 5-10 watt with power output about 100 watt. Whether you want to create your own radio station, transmit the music around the house, or simply create a wirele

ss link between your iPod and a receiver in your car, this transmitter will let you do these things easily. With BA1404 HI-FI Stereo transmitter you will be able to transmit MP3 music from your iPod, computer, discman, walkman, TV / SAT receiver, and many other audio sources. The above FM transmitter design is a result of many hours of testing and tweaking. The goal was simple; to test many existing BA1404 transmitter designs, compare their performance, identify weaknesses and come up with a new BA1404 transmitter design that improves sound quality, has very good frequency stability, maximizes transmitter`s range, and is fairly simple for everyone to build. We are happy to announce that this goal and expectations have been met and even exceeded. The transmitter can work from a single 1. 5V cell battery and provide excellent crystal clear stereo sound. It can also be supplied from two 1. 5V battery cells to provide the maximum range. One of the qualities of BA1404 FM transmitter is excellent frequency stability. This is mainly due to a use of high quality 3. 5 turn variable coil. Tunable RF coils are ideal for precise frequency tuning because their magnet wire is halfway embedded within the plastic, which minimizes frequency drifts. Regular air coils are not preferred for professional broadcasting because the coil expands and contracts with temperature changes. That`s the very reason why variable coil was chosen as a...
