The Blonder Tongue BIDA 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. Three models are
available; the #5400-73 with a 47 to 750 MHz bandpass and the #5400-53 and -55 with 47 to 550 MHz bandpass. The
basic amplifier is configured for one-way operation. Optional field installable modules provide two-way capability with
either a passive or active sub-channel return path.
The #5400-55 has a flat operating gain of approximately 50 dB. The #5400-53, and -73 have a gain of about 33 dB
(see Specifications for typical values of each model). Lower operating gains can be achieved by adjusting the variable
attenuator. All models 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
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
The aluminum chassis is designed to provide excellent heat dissipation thus allowing operation at high ambient
temperatures with no degradation of performance or reliability.
