Application Notes
Termination
In high frequency applications reflections occur if signals
are not properly terminated To minimize reflection coaxial
cable with matching characteristic 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 75
tics impedance and RG58 has 50
ance
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
load capacitor froms a pole to incease stability by adding
more phase margin to the overall system The desired per-
formance depends on the value of the isolation resistor the
bigger the isolation resistor the more damped the pulse
response becomes A 50
