19F_LO Synthesis
6.1.3
The 19F_LO-signal is created by a phase locked oscillator. The oscillator itself is of
conventional LC-Colpitts type. The dividers (1/N rf-divider and 1/M reference-di-
vider) as well as the phase detector of the PLL loop are integrated in a synthesizer
IC (SP8861).
Mixer
6.1.4
The 19F_OPT (f
2H
) and 19F_LO (f
pll
) signals are processed in an active Gilbert
mixer (SIEMENS, TDA6130X4). The Deuterium signal is lowpass filtered before
reaching the RF-port of the mixer.
19F_TR Signal Path
6.1.5
A high pass filter with finite zeroes at the local oscillator frequency (f
pll
) suppresses
LO-signals appearing at the mixer output, so that the following amplifier stages are
not driven into saturation. The filter also provides impedance matching of the mixer
output to the input of the following amplifier. After a first amplifier stage a lowpass
filter suppresses harmonics of the local oscillator signal and unwanted mixing prod-
ucts above the 19F frequency. A second amplifier stage provides enough power at
the 19F_TR output and the following highpass filters Deuterium frequencies (f
2H
).
A SPDT-bipolar switch controlled by the transmitter pulse (TP) is used to switch off
the 19F_TR frequency during acquisition and a resistive attenuator improves VSWR
at the 19F_TR output.
IIC Bus EEPROM
6.1.6
Production and performance data can be stored in an IIC-bus accessible EEPROM.
19F Lock Operation
6.1.7
For information about 19F lock operation see the according section (Operation) in
this manual.
