C Band Satellite Transponder Block Diagram

Explain simplified block diagram of satellite transponder 1 single convention in c band 2 double conversion in ku band.

C band satellite transponder block diagram.

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. 1 duplexer is a two way microwave gate. The block diagram of transponder is shown in below figure.

Figure 1 shows the block diagram of the assumed sat ellite mounted system. Block diagram of a typical ttc transponder. Block diagram of a linear transponder the digital transponders usually take advantage of the fm wide so we can use our equipment without modifications between 1 200 bd and 9 600 bd. Why do some satellites have two transponders while others have twenty four.

Figure 2 block diagram of the tt c transponder figure 2. 8 m 10 m. Usually in geo operate at the c band around 6 ghz. First it adopts a 2 hop configuration for communication and second it has a digital transponder system on board.

The ttc transponder on the spacecraft plays the role of radio frequency interface with the ground. Signals received by an antenna from the earth station at an uplink frequency of 6 ghz are fed to a low noise amplifier lna which comprises of gaas fet amplifier. Each transponder is. 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. Block diagram of. It receives uplink signal from the satellite antenna and transmits downlink signal to the satellite antenna. The satellite is distinctive in the following two points.

A receive chain which tracks the uplink telecommand signal received from ground demodulates the command data tc and forwards this to the onboard data handling unit obdh. May 2012 dec 2012. The function of each block is mentioned below. The satellite transponder typically works in either the c band 4 8ghz or the ku band 12 18ghz and these are for the downlink from the satellite to the earth station.

Extended c band communications satellite will be examined briefly here. Block diagram of satellite transponder the signal received from the satellite is processed. A typical single conversion transponder operating at 6 4 ghz c band is shown in figure 1. The block diagram of transponder is shown in below figure.

In the 2 hop configuration communication the user uplink. Duplexer is a two way microwave gate.
