Power Supply Bypassing
Bypassing the power supply is necessary to maintain low
power supply impedance across frequency. Both positive and
negative power supplies should be bypassed individually by
placing 0.01 μF ceramic capacitors directly to power supply
pins and 2.2 μF tantalum capacitors close to the power supply
pins.
Termination
In high frequency applications, reflections occur if signals are
not properly terminated.

To minimize reflection, coaxial cable with matching charac-
teristic impedance to the signal source should be used. The
other end of the cable should be terminated with the same
value terminator or resistor. For the commonly used cables,
RG59 has 75Ω characteristic impedance, and RG58 has
50Ω characteristic impedance.
Driving Capacitive Loads
Amplifiers driving capacitive loads can oscillate or have ring-
ing at the output. To eliminate oscillation or reduce ringing, an
isolation resistor can be placed as shown below in
The combination of the isolation resistor and the load capac-
itor forms a pole to increase stability by adding more phase
margin to the overall system. The desired performance de-
pends on the value of the isolation resistor; the bigger the
isolation resistor, the more damped the pulse response be-
comes. For LM7171, a 50Ω isolation resistor is recommended
for initial evaluation.
