Abstract
Harmonics of X-band (8.4-GHz) spacecraft transmitter systems can be used to measure the performance characteristics of higher frequency deep space communications links. The Galileo X-band transmitter system was measured at the second, third, and fourth harmonics (16.8 GHz, 25.2 GHz, and 33.6 GHz, respectively). The effective isotropic radiated power was determined to be approximately 52 dBm at 16.8 GHz, 47 dBm at 25.2 GHz, and 25 dBm at 33.6 GHz. These values can be useful, depending upon the sensitivity of the Earth-based receiving system and the distance of the spacecraft from Earth.
