So it is possible to build a receiving system.
C band satellite transponder block diagram.
It receives uplink signal from the satellite.
Duplexer is a two way microwave gate.
Rain attenuation and sky noise is low at 4 ghz downlink frequency of c band.
The function of each block is mentioned below.
Signals traveling from earth to satellites must travel through the atmosphere.
Satellite communication system block diagram.
The block diagram of transponder is shown in below figure.
The function of each block is mentioned below.
The communication is through a telecommunication link established between the control station on the ground and the satellite.
Each transponder is amplified by either a travelling wave tube am plifier twta or a solid state power amplifie r.
Extended c band is most popular because of less propagation problem.
Satellite transponder does this operation.

Maurizio di paolo emilio.
It receives uplink signal from the satellite antenna and transmits downlink signal to the satellite antenna.
The ttc transponder on the spacecraft plays the role of radio frequency interface with the ground.
The block diagram of transponder is shown in below figure.

8 m 10 m.
The number of transponders or channels indicates the capacity of the satellite.
A transponder is typically composed of.
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.
This is for c band satellite band.

The same is explained below with the use of the block diagram.
A communications satellite s transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas.
The basic block diagram of an vsat earth station transmitter is as shown in fig 2.
It is mainly used in satellite communication to transfer the received signals.
A block diagram of a transponder.
1 duplexer is a two way microwave gate.
We can easily understand the operation of transponder from the block diagram itself.
Usually in geo operate at the c band around 6 ghz.
Why do some satellites have two transponders while others have twenty four.
