ETL Systems Alto ALT-G2S-L1-144 L-Band Variable Gain Amplifier 950–2150 MHz

ETL Systems Alto ALT-G2S-L1-144 L-Band Variable Gain Amplifier 950–2150 MHz

The ETL Systems Alto ALT-G2S-L1-144 is an L-band smart amplifier module operating from 950–2150 MHz. It provides variable gain and positive slope compensation for signal-level adjustment and cable-loss compensation in satellite communications and RF distribution systems.

Gain is adjustable across a nominal 0–24 dB range in 0.5 dB steps. The specified gain endpoints apply at 2150 MHz with a 2 dB slope setting. Positive slope compensation provides a standing 2 dB slope with up to 7 dB additional adjustment, using a pivot point at 2150 MHz.

The module supports user-selectable 18 V LNB powering at up to 500 mA per channel and 10 MHz reference injection through a compatible GENUS chassis. Available RF interfaces include 50Ω or 75Ω BNC connectors.

Each hot-swappable amplifier occupies one slot in a compatible GENUS 2U chassis. Local and remote monitoring and control are provided through the selected chassis platform.
