Type | HEMT cooled | ||
Channels | 8 | (upper/lower band of 2 polarizations in 2 horns each) | |
Receiver Noise | 30-50K | depending on frequency band: channels 1&2 (horn A; offset horn) and channels 3&4 (horn B; main offset) | |
Frequency range | 33 GHz - 50 GHz | (for details see conversion plan) | |
Polarization | LHC/RHC | 2 horns | |
Calibration | Noise diode | noise figures for high channels low channels | |
1. IF | 5 - 10 GHz | (Synthesizer 1 = 10.75 - 13.75 GHz x 4) | |
2. IF | 0 - 4 GHz | lower band (Synthesizer 21 = 10 GHz) | |
