The RF frequency range is defined by the oscillator frequency range and the intermediate frequency.
The gain is defined as the transducer gain (measured in Fig.7) plus the voltage transformation ratio of L3 to L2
(10 : 2, 15.4 dB including transformer loss).

All S-parameters are referred to a 50
system.
Measured with RF input voltage of 97 dB

Limits are related to the tank circuits used in Fig.7. Frequency bands may be adjusted by the choice of external
components.
The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
V
P
