Amplifier is used in an FM transmitter to increase the level of a signal suitable for transmission
There are 3 stages of an FM transmitter which allow you to transmit information over the FM band. These 3 stages need to be integrated into a single circuit to form what is known as a 3 stage FM transmitterA modulator circuit to add the information to be transmitted to the carrier wave produced by the oscillator. This is done by varying some aspect of the carrier wave. The information is provided to the transmitter either in the form of an audio signal, which represents sound, a video signal, or for data in the form of a binary digital signal. In an FM (frequency modulation) transmitter the frequency of the carrier is varied by the audio signal.Many other types of modulation are also used. In large transmitters the oscillator and modulator together are often referred to as the exciter. An RF power amplifier to increase the power of the signal, to increase the range of the radio waves.An impedance matching (antenna tuner) circuit to match the impedance of the transmitter to the impedance of the antenna (or the transmission line to the antenna), to transfer power efficiently to the antenna. If these impedances are not equal, it causes a condition called standing waves, in which the power is reflected back from the antenna toward the transmitter, wasting power and sometimes overheating the transmitter.
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
LNA - Low Noise Amplifier
This is a vague question. Which transistor, and what is the make of the FM trasmitter? What do you really want to do, design an FM transmitter or repair an existing one?
Yes, but it will be less efficient than one designed for FM.
Sadly, this website doesn't include the capabilites of storing andreproducing drawings.Any FM transmitter will have the following circuit blocks:power supplyaudio amplifier/equalizerreactance modulatoroscillatorpre-emphasis networkfrequency multiplierbandpass networkpower amplifierantenna matching networktransmitting antennaThe power amplifier will be designed for the required output power,or somewhat more."km" is not a unit of power.
There are several different devices that can be used with an FM mp3 transmitter. Devices such as a portable CD player, portable DVD player, and satellite radios can be used with an FM mp3 Transmitter.

Yes. FM transmitters will work with a car stereo.

A wireless FM transmitter is used to play music files through ones FM radio through wireless connectivity. One can hook up their device and as long as it is set within the proximity of the FM transmission, it will be able to play the music.
As FM is transmitted using VHF, the transmitting range is more a matter of Line of Sight than transmitter power as these frequencies only follow straight lines.

From the research I have done, the best FM transmitter will depend on what you are using it for. Two that I found come rated with 4 and 1/2 stars are the Belkin TuneCast F8Z498-P FM Transmitter and the Griffin itrip auto fm transmitter for ipod.

an iTrip transmitter is an FM transmitter that is compatible with Apple iPods. You can plug in your iPod, and it will play your music through an intermittent FM station.
