APPLICATION NOTES
Input circuit
The SL610C, SL611C and SL612C are normally used with
pins 5 and 6 connected together and with the input connected
via a capacitor as shown in Fig.2.
The input impedance is negative between 30MHz and
100MHz (SL610C, SL611C only) and is shown in Fig.3. The
source and inductive is should be shunted by a 1k
resistor to
prevent oscillation.
An alternative circuit with improved noise figure is shown in
Fig.4.
Output circuit
The output stage is an emitter follower and has a negative
output impedance at certain frequencies as shown in Fig.5.
To prevent oscillation when the load is capacitive a 47
resistor should be conncted in series with the output.
AGC
When pin 7 is open circuit or connected to a voltage less
than 2V the voltage gain is normal. As the AGC voltage is
increased there is a reduction in gain as shown in Fig.6. This
reduction varies with temperature.
