Description
The RMDA series of 19" rack mount amplifiers are completely self-contained broadband distribution amplifiers,
designed specifically for signal distribution systems requiring the low distortion characteristics only available using
hybrid CATV integrated circuits. Useful either in systems which use a "cable drop" as a signal source or as the
launch amplifier in a headend, these amplifiers are available in various gain versions with four different bandwidths,
47 to 550 MHz, 47 to 750 MHz, 47 to 860 MHz or 47 to 1000 MHz.
These amplifiers are available with one or two hybrid amplifier gain blocks. The use of two gain block units with
interstage controls provides superior noise performance along with an extended range of gain and slope. The single
gain units provide good electrical performance at a modest price. The combination of these two architectures in the
RMDA line results in models with a wide range of performance features to satisfy simple or stringent applications.
The series provides flat operating gain which can be reduced with a variable attenuator. Gain and slope controls are
located on the front panel for fast set-up and adjustment.
Two 20 dB test points are provided to permit testing without interruption of service.
Hybrid IC modules enable the RMDA to operate at high output levels while retaining low distortion
characteristics.
The aluminum chassis is designed to provide excellent heat dissipation, thus allowing operation at high ambient
temperatures with no degradation of performance or reliability.
