OPERATING NOTES
The amplifiers are intended for use directly coupled, as
shown in Fig 8.
The seventh stage in an untuned cascade will be giving
virtually full output on noise.
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 choice of
network is also controlled by the need to avoid distorting the
logarithmic law; the network must give unity voltage transfer at
resonance A suitable network is shown in Fig 9. The value of
C1 must be chosen so that at resonance its admittance equals
the total loss conductance across the tuned circuit Resistor R1
may be introduced to improve the symmetry of filter response,
providing other values are adjusted for unity galn at
resonance.
A simple capacitor may not be suitable for decoupling the
output line if many stages and fast rise times are required.
Alternative arrangements may be derived, based on the
parasitic parameters given.
Values of positive supply line decoupling capacitor
requlred for untuned cascades are given below. Smaller
values can be used in high frequency tuned cascades.

The amplifiers have been provided with two earth leads to
avoid the introduction of common ground lead inductance
between input and output circuits. The equipment designer
should take care to avoid the subsequent introduction of such
inductance.
The 500pF supply decoupling capacitor has a resistance
of, typically, 1 0Q. It is a junction type having a low breakdown
voltage and consequently the positive supply current will
increase rapidly if the supply voltage exceeds 7.5V (see
Absolute Maximum Ratings).
