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 moreWhat does transponder stand for?
A transponder (short for transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) is an electronic device that produces a response when it receives a radio-frequency interrogation.

Early Bird had just one transponder capable of sending just one TV channel. The Boeing 702 series of satellites, in contrast, can have more than 100 transponders , and with the use of digital compression technology each transponder can have up to 16 channels, providing more than 1,600 TV channels through one satellite.
Read moreHow much data can a satellite transmit?
For consumer satellite Internet, the allowance can typically range from 200 MB per day to 25 GB per month . A shared download carrier may have a bit rate of 1 to 40 Mbit/s and be shared by up to 100 to 4,000 end users.
Read moreWhat kind of signals do satellites use?
Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
Read moreWhat frequency do satellites use?
An AM radio operates at a frequency between 535-1605 kilohertz (kHz), so a station at 800 kHz has waves cycling 800,000 times per second. A signal from a Ka-band satellite operates at a much higher frequency of around 28 gigahertz (GHz) , 28,000,000,000 times per second.11 Şub 2022
