C band satellite transponder block diagram.

Extended c band communications satellite wi ll be examined briefly here. It is mainly used in satellite communication to transfer the received signals. Each transponder is amplified by either a travelling wave tube am plifier twta or a solid state power amplifie r. The block diagram of transponder is shown in below figure.

A communications satellite s transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. An input low noise amplifier lna designed to. A block diagram of a transponder. Satellite transponder does this operation.

The number of transponders or channels indicates the capacity of the satellite. The block diagram of transponder is shown in below figure. Satellite communication system block diagram. The same is explained below with the use of the block diagram.

The communication is through a telecommunication link established between the control station on the ground and the satellite. The function of each block is mentioned below. Duplexer is a two way microwave gate. So it is possible to build a receiving system.

The basic block diagram of an vsat earth station transmitter is as shown in fig 2. The ttc transponder on the spacecraft plays the role of radio frequency interface with the ground. 8 m 10 m. The two way communication is established with the help of transponder a com satellite has multi transponder per satellite has in creased over the year a satellite with 2 transponder can support a signal t v channel or 240 telephone lines a satellite with 48 transponder can accommodate 4000t.

May 2012 dec 2012. We can easily understand the operation of transponder from the block diagram itself. The block diagram of transponder we can easily understand the operation of transponder from the block diagram itself. Block diagram of a typical ttc transponder.

An input band limiting device an input band pass filter. A transponder is typically composed of. It receives uplink signal from the satellite. This is for c band satellite band.

Signals traveling from earth to satellites must travel through the atmosphere. Explain simplified block diagram of satellite transponder 1 single convention in c band 2 double conversion in ku band. Extended c band is most popular because of less propagation problem. It receives uplink signal from the satellite antenna and transmits downlink signal to the satellite antenna.

Why do some satellites have two transponders while others have twenty four. Rain attenuation and sky noise is low at 4 ghz downlink frequency of c band. 1 duplexer is a two way microwave gate.
