1 GHz Broadband Drop Amplifier

The TDA-112 is a broadband 12 dB gain amplifier ideally suited for long cable drops or multiple subscriber outlets. The TDA-112 features a bandwidth from 5 MHz to 1 GHz, gain of 12 dB, flatness 1 dB across bandwidth. The unit is built in a rugged zinc diecast housing with two mounting tabs and a built-in ground lug for convenience. The amplifier is powered by 12V DC utilizing a 120V AC plug-in transformer (220V optional). Both the amplifier and transformer power connectors are "F" type, allowing the use of coaxial cable which is low in cost and readily available. A 6' RG-59 jumper is provided for convenience.
