Televes DTKom Broadband Multiband Amplifier

Product Overview

The DTKom line broadband multiband amplifier is a high-power amplifier designed for VHF/UHF signals. It features multiple controls on the front end, utilizing components that minimize the total noise figure. The amplifier is equipped with one VHF/UHF input and one output (line). It supports remote power feeding, allowing it to power or be powered via direct current through the coaxial cable.

Key features include separate amplification to minimize intermodulation between bands and provide high output levels, and the use of Push-Pull technology to guarantee levels in the 123 dBμV range for terrestrial signals. It also includes a high-performance, low-power consumption switch-mode power supply and a high-screening Zamak chassis for efficient cooling. The design incorporates pre-equalization and equalization stages, an intuitive front cover with adjustments and a block diagram, and can be wall-mounted using screws.

Application Example

A block diagram illustrates the signal flow for the amplifier system. It shows input signals going through a 'Headend' stage, then to the amplifier (Ref. 5338), with options for remote power (Telealim. DC) and output to TV signals. A note indicates that Ref. 5338 can line-power another Ref. 5338 with 700mA/9V.
