The BIDA 5800 and 5900 Series are professional quality, two-way broadband indoor distribution amplifiers. These amplifiers are ideal for multi-channel RF distribution systems for which the input source is a “cable drop” or the output of a MATV/ SMATV/CATV headend.

The BIDA 5800 Series features models having RF bandwidths of 550,750, 860 and 1000 MHz. Push-pull and power-doubling hybrid amplifier technologies are available on the two series. Both the BIDA 5800 and 5900 series are factory equipped for 2-way operation. The 5800 series has a 36/49 MHz split where the 5900 series has a 42/54 MHz (reverse/forward) split. Both series leave the factory set for passive return path operation. Active return path operation can easily be accomplished by reconfiguring a few internal jumpers.

The BIDA 5800/5900 Series utilizes an external power transformer providing 26 VAC to the amplifier. This enables the amplifiers to be remotely powered via low voltage AC wiring should a 120 VAC electrical outlet not be in close proximity to the desired amplifer location.
