discussion of the various elements
Figure 12: Block Diagram of Receiver Concept
The Receiver operates in a straight forward fashion for Deuterium. Other lock sub-
stances are mixed to f
2H
+1MHz.
The preamplified 2H lock signal is filtered and amplified once more in the High Fre-
quency section of the Receiver. Afterwards it is actively mixed with the 2H_LO sig-
nal from the transmitter. This results (due to the phase switching receiver) in an
audio frequency of 3.3 kHz. The resulting signal is once again amplified, filtered
and digitized in the low frequency section.
At the Receiver input the Lock signal is between -75 and -15dBm.
The variable gain amplifiers in the HF and LF sections compensate the different in-
put levels. The output amplitude is then optimized for the best A/D converter per-
formance. The total possible compensation of 60 dB is divided between the HF and
LF sections (30 dB each).
