Technical Documentation of the C/X-Band Receiver 4 - 9.3 GHz (S45mm)
| Type | HEMT cooled | |||
| Channels | 8 | upper/lower broad- and narrowband of 2 polarizations | ||
| Receiver Noise | 20K | |||
| Frequency range | 4 GHz - 9.3 GHz | 4 - 8 GHz (C-Band) / 5.3 - 9.3 GHz (X-Band) | ||
| Polarization | LHC/RHC | single horn | ||
| Calibration | Noise diode | 5 MHz phase cal | ||
| IF lower band | 0 - 4 GHz | 0 - 2.5 GHz | 1,8 - 2.0 GHz | |
| IF upper band | 0 -2.5 GHZ | 1,8 - 2.0 GHz | ||
| Synthesizer frequency for fsky at center of: | 4 GHz IF | 2.5 GHz IF | 200 MHz IF | |
| Highband (Ch.1, 2, 5, 6): | fsynth.4 = 8.0/9.3GHz | fsynth.4 = 8.0/9.3GHz | fsynth.5 = fsky + 1.9GHz | |
| Lowband (Ch.3, 4, 7, 8): | fsynth.3 = 4.0/5.3GHz | fsynth.1/2 = fsky - 1.9GHz (1: fsky = 4 - 6 GHz / 2: fsky = 5.9 - 7.3 GHz | ||
