C Band Satellite Transponder Block Diagram

A block diagram of a transponder.

C band satellite transponder block diagram.

Extended c band is most popular because of less propagation problem. A communications satellite s transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. Satellite transponder does this operation. The same is explained below with the use of the block diagram.

An input low noise amplifier lna designed to. An input band limiting device an input band pass filter. Satellite communication system block diagram. The block diagram of transponder is shown in below figure.

Extended c band communications satellite wi ll be examined briefly here. Why do some satellites have two transponders while others have twenty four. It receives uplink signal from the satellite antenna and transmits downlink signal to the satellite antenna. May 2012 dec 2012.

The function of each block is mentioned below. 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. Each transponder is amplified by either a travelling wave tube am plifier twta or a solid state power amplifie r. Signals traveling from earth to satellites must travel through the atmosphere.

The block diagram of transponder is shown in below figure. A transponder is typically composed of. Explain simplified block diagram of satellite transponder 1 single convention in c band 2 double conversion in ku band. The communication is through a telecommunication link established between the control station on the ground and the satellite.

Maurizio di paolo emilio. The basic block diagram of an vsat earth station transmitter is as shown in fig 2. As shown in the figure satellite transponder receives signal of say 6175 mhz from the earth it converts the same to 3950 mhz by substracting it using lo of 2225 mhz. The number of transponders or channels indicates the capacity of the satellite.

It is mainly used in satellite communication to transfer the received signals. Block diagram of a typical ttc transponder. Duplexer is a two way microwave gate. 1 duplexer is a two way microwave gate.

This is for c band satellite band. We can easily understand the operation of transponder from the block diagram itself. It receives uplink signal from the satellite. The block diagram of transponder we can easily understand the operation of transponder from the block diagram itself.

The function of each block is mentioned below. Usually in geo operate at the c band around 6 ghz. The ttc transponder on the spacecraft plays the role of radio frequency interface with the ground.
