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 1kΩ resistor to prevent oscillation. An alternative circuit with improved noise figure is shown in Fig.4. 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. 5 3 6 4 8 Fig.4 Alternative input circuit 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 47Ω resistor should be conncted in series with the output.
