Technical Documentation of the Q-Band Receiver 33 -50 GHz (S7mm)

TypeHEMT cooled
Channels8 (upper/lower band of 2 polarizations in 2 horns each)
Receiver Noise30-50K depending on frequency band: channels 1&2 (horn A; offset horn) and channels 3&4 (horn B; main offset)
Frequency range33 GHz - 50 GHz (for details see conversion plan)
PolarizationLHC/RHC 2 horns
CalibrationNoise diode noise figures for high channels low channels
1. IF5 - 10 GHz (Synthesizer 1 = 10.75 - 13.75 GHz x 4)
2. IF0 - 4 GHz lower band (Synthesizer 21 = 10 GHz)
0 -2.5GHZ upper band (Synthesizer 22 = 5 GHz)
Synth.1 frequency for fsky at center of:4 GHz IF2.5 GHz IF300 MHz IF0.5-1 GHz IF
Highband (Ch.1, 3, 5, 7): fsynth.1 =(fsky + 8.0GHz)/4(fsky + 8.75GHz)/4(fsky + 9.85GHz)/4(fsky + 9.25GHz)/4
