Reverse Amplifier 93146
The reverse amplifier type 93146 provides a plug-in option for Compact amplifiers, to
enable two-way amplification in support of bi-directional services.
enable two-way amplification in support of bi-directional services.
The reverse amplifier’s fixed-value plug-in pads provide maximum user-friendliness, enable sharing
common plug-in accessories with Compact amplifiers, thereby lowering operator’s cost of spares.

Furthermore, the unit features improved flatness and re-arranged test point reference for more
straightforward reverse path alignment, and common reference for signal injection point and test
point. Both test point and signal injection point utilizes directional couplers, to ensure a precise
reverse alignment that is virtually independent of impedance mismatches in the network.

The reverse amplifier features push-pull circuits, which are extremely overloading proof with very
low inter-modulation distortion at high output levels. The reverse amplifier is equipped with
equalizer and attenuator at the output.
