The function of each block is mentioned below.
C band satellite transponder block diagram.
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.
8 m 10 m.
A block diagram of a transponder.
The block diagram of transponder is shown in below figure.
The same is explained below with the use of the block diagram.
Satellite transponder does this operation.
Why do some satellites have two transponders while others have twenty four.
A transponder is typically composed of.
The ttc transponder on the spacecraft plays the role of radio frequency interface with the ground.
It receives uplink signal from the satellite.
The number of transponders or channels indicates the capacity of the satellite.
The block diagram of transponder we can easily understand the operation of transponder from the block diagram itself.
So it is possible to build a receiving system.
An input low noise amplifier lna designed to.
Extended c band communications satellite wi ll be examined briefly here.
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.
Duplexer is a two way microwave gate.
1 duplexer is a two way microwave gate.
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.
Usually in geo operate at the c band around 6 ghz.
The basic block diagram of an vsat earth station transmitter is as shown in fig 2.
Satellite communication system block diagram.
Signals traveling from earth to satellites must travel through the atmosphere.

We can easily understand the operation of transponder from the block diagram itself.
Rain attenuation and sky noise is low at 4 ghz downlink frequency of c band.
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.
Each transponder is amplified by either a travelling wave tube am plifier twta or a solid state power amplifie r.
