Transponders |
|
| |
|
|

-
The transponder is the “brains” of the
satellite - provides the connection between
the satellite’s receive and transmit
antennas.
-
Satellites can have 12 to 96 transponders
plus spares, depending on the size of the
satellite.
-
A transponder bandwidth can frequently be 36
MHz, 54 MHz, or 72 MHz or it can be even
wider.
-
A transponders function is to
- Receive the signal, (Signal is one
trillion times weaker then when transmitted)
- Filter out noise,
- Shift the frequency to a down link
frequency (to avoid interference w/uplink)
- Amplify for retransmission to ground
