*Decoupling Impedance is 1 kOhm.
The CZ81X0 Series Amplifiers are designed for application in 50 ohm
systems. Three external capacitors and a decoupling impedance are
required. The decoupling impedance must be large in comparison to
the 50 ohm load to minimize gain reduction. Data sheet curves are
based on the noted decoupling impedance. The external capacitors
determine the low frequency response of the Amplifier.
