RMDA 1000-42P – Overview
The Blonder Tongue RMDA 1000-42P is a completely self-contained broadband distribution amplifier, designed specifically for signal distribution systems requiring the low distortion characteristics only available using hybrid CATV integrated circuits. With a forward bandwidth of 54 to 1000 MHz and a gain of 42 dB, the RMDA 1000-42P is useful in either systems that use a “cable drop” as a signal source or as the launch amplifier in a headend.
The RMDA 1000-42P features power doubling hybrid amplifier technology for high RF output levels and low distortion. The amplifier 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. The unit is housed in a 1RU aluminum chassis, providing exceptional heat dissipation and allowing operations at high ambient temperatures with no degradation of performance or reliability. Two -30 dB test points at the input and output are provided to permit testing without interruption of service.
