What is a bent pipe transponder?
The bent-pipe transponder, used in conventional satellites, converts the frequency of the uplink signal issued from earth stations, amplifies it, and downlinks the signal back to earth sta- tions.
What is the difference between a transmitter and a transponder?
The difference between the two is that transceivers interface electrically with the host system using a serial interface, whereas transponders use a parallel interface to do so. In this view, transponders provide easier-to-handle lower-rate parallel signals, but are bulkier and consume more power than transceivers.
What is double conversion transponder?
Double conversion in Ku band
These transponders normally employ a double frequency conversion scheme. It is easier to design filters, amplifiers and equalisers at an intermediate frequency (IF) such as 1100MHz than at 14 or 11 GHz, so the incoming 14 GHz carrier is translated to an IF around 1GHz.
Which of the following is one of the components of satellite transponder?
A transponder is typically composed of: An input band-limiting device (an input band-pass filter), An input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station (normally very weak, because of the large distances involved.)
