Wideband Satellite Systems Operator Course (WSSOC) Annex A Practice Test

The concept being tested is where the Ka-band uplink (TX) signal is upconverted to in the transmitter. In Ka-band satellite links, the uplink carrier is centered in the vicinity of 29 GHz, and the IF signal is translated up to this Ka-band frequency using a mixer and local oscillator. Therefore, 29 GHz is the standard Ka-band TX translation frequency used in this context, which is why it’s the correct choice. The Ka-band range spans roughly 26.5 to 40 GHz, and 29 GHz sits squarely within that band as a common reference uplink frequency.
