A communications satellite’s transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. It is mainly used in satellite communication to transfer the received signals .
Read moreHow many transponders does a satellite have?
A typical satellite has up to 32 K u-band or 24 C-band transponders, or more for K u/C hybrid satellites . Typical transponders each have a bandwidth between 27 and 50 MHz.
Read moreHow many channels does a transponder have?
Each satellite transponder can carry 2 channels of regular (analog) TV programs, or 6 channels of digital TV programs .
Read moreWhy uplink and downlink frequency is different for satellite system?
It say basically the power at ground stations is more as compared to power available at satellites .So generally frequency for uplink is kept higher than the downlink. There is greater attenuation due to rain when the signal frequency is high.so downlink is also kept at lower frequency.
Read moreWhat is satellite uplink and downlink frequency?
Uplink frequency is the frequency at which, the first earth station is communicating with satellite . The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.
Read moreWhy uplink frequency is higher in satellite communication?
In satellite communication, the uplink frequency is higher than the downlink frequency because the attenuation level increase with an increase in frequency . The power at the ground station (Base Station) is more than compared to the power available at the satellite.
