Description

250 to 2150 MHz DBS amplifi er with 25 dB gain, LNB powering and slope compensation.

Situation

DBS 250 to 2150 MHz signals from a dual LNB need to be powered, polarity locked and amplifi ed to feed multiple switches.

Solution

28 dB DUAL LNB Amplifier Model SD TA282-T power a DBS dual LNB, amplifi es the signals and pre-emphasizes high frequencies to compensate for cable slope.
