OUR PART #  BIDA550-30

The Blonder Tongue BIDA (model 5400-53) is a completely self-contained broadband indoor distribution amplifier designed specifically for CATV and SMATV signal distribution systems which use a "cable drop" as a signal source.  The basic amplifier is configured for one-way operation.   Optional (sold separately) field-installable modules provide two-way capability with either a passive or active sub-channel return path.

The 5400-53 model has a gain of about 33 dB (see page 5 of the User Manual for typical values and other specifications).  Lower operating gains can be achieved by adjusting the variable attenuator.  This model can be attenuated over a range of 15 dB.  Gain and slope controls are located on the front panel for easy set-up and adjustment.  Two -30 dB backmatched test points are provided to permit testing without interruption of service.

In applications where input signals are too high or where greater cable equalization is necessary, the BIDA can be reconfigured by using plug-in attenuators and cable slope equalizers to meet particular requirements.  Push-pull, hybrid IC modules enable the BIDA 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.
