LED and Laser Transmitters LED Transmitter Light - emitting diode (LED) is a standard light source that carries low speed signals at short distances. LED light source is an all plastic fiber that transmits visible light. LED put out lower power and a bigger output pattern than laser light sources. LEDs have less bandwidth and are limiting to operate up to about 250Mhz or about 200Mbs. LED light sources do not contain hazardous material and last longer‚ about 10‚000 hours. Bulbs generate less heat

COOLING TECHNIQUES IN TRANSMITTER Introduction In modern A.M. transmitters power valves are used in the PA and modulator stages‚ which are condensed vapour cooled ceramic tetrodes. In the old generation transmittes‚ triodes are used in the PA‚ modulator and exciter stages. Both the tetrodes and triodes tubes are capable of being operated at high voltages (11 kV DC) and large anode current of the order of 50 Amps. They also draw large filament current of about 620 Anps at 24 volt CQK-350

Amplitude modulation is when the modulating audio is combined with a radio frequency carrier is such a way that the total wave power is made to vary in accordance with the modulating audio. The normal type of AM is double sideband or‚ to be more specific‚ double sideband full carrier. Recall that the carrier does not convey any intelligence

gKit 32. TWO STAGE FM TRANSMITTER This Kit is a powerful two stage‚ 9V FM transmitter (Tx) with a range of up to 1 kilometer in the open. It uses an RF transistor in its output stage. Distance of transmission is critically dependent on the operating Conditions (in a building or out on the open)‚ type of aerial used (single wire or dipole)‚ operating voltage (12V is better than 6V) and if the circuit is peaked for maximum performance. The kit is constructed on a single-sided printed circuit board

are two main types of fibre optic transmitter that are in use today. Both of them are based around semiconductor technology: • Light emitting diodes (LEDs) • Laser diodes Semiconductor optical transmitters have many advantages. They are small‚ convenient‚ and reliable. However‚ the two different types of fibre optic transmitter have very different properties and they tend to be used in widely different applications.
