Notes to the characteristics
1. The values have been corrected for hybrid and cable losses. The symmetrical output impedance of
the circuit is 100 Ω.
2. The input level of a N + 5 − 1 MHz signal (just visible).
3. The gain is defined as the transducer gain (measured in Fig.3) plus the voltage transformation ratio
of L6 to L7 (6:1, 16 dB).
4. All S parameters are referred to a 50 Ω system.
5. The input power is defined as the power delivered by the generator on a 50 Ω load.
6. The frequency shift is defined for a variation of power supply from;
a) VP = 12 V to VP = 10.8 V
b) VP = 12 V to VP = 13.2 V.
In both cases the frequency shift is below the specified value.
7. The frequency drift is defined for a variation of ambient temperature from;
a) Tamb = 25 °C to Tamb = 0 °C
b) Tamb = 25 °C to Tamb = 50 °C
In both cases the frequency shift is below the specified value.
