OPERATING NOTES
The amplifier is designed to be directly coupled (seeFig.5)
The fourth stage in an untuned cascade will give full output
on the broad band noise generated by the first stage.
Noise may be reduced by inserting a single tuned circuit in
the chain As there is a large mismatch between stages a
simple shunt or series circuit cannot be used The network
chosen must give unity voltage gain at resonance to avoid
distorting the log law The typical value for input impedance is
500
in parallel with 5pF and the output impedance is typically
30
.
Although a 1nF supply line decoupling capacitor is
included in the can an extra capacitor is required when the
amplifiers are cascaded Minimum values for this capacitor
are: 2 stages - 3nF, 3 or more stages 30nF
In cascades of 3 or more stages care must be taken to
avoid oscillations caused either by inductance common to the
input and output earths of the strip or by feedback along the
common video line The use of a continuous earth plane will
avoid earth inductance problems and a common base
amplifier in the video line isolating the first two stages as
shown in Fig 6 will eliminate feedback on the video line

Note:- Overload occurs when the input signal reaches a level sufficient to forward bias the base-collector junction to the input
