ETL Systems Alto ALT-G1S-L1-104 L-Band Variable Gain Amplifier Module 850–2150 MHz

ETL Systems Alto ALT-G1S-L1-104 L-Band Variable Gain Amplifier Module 850–2150 MHz

The ETL Systems Alto ALT-G1S-L1-104 is an L-band smart amplifier module operating from 850–2150 MHz. Designed for a compatible GENUS 1U chassis, it combines variable gain, adjustable slope, and high linearity for RF signal conditioning and level balancing.

The amplifier provides nominal gain adjustment from 0–28 dB, with fine 0.25 dB steps in manual gain mode. Its 0–8 dB slope control, pivoting at 2150 MHz, supports compensation for frequency-dependent signal loss. Manual gain and automatic output-level control modes provide flexibility for different signal requirements.

At maximum gain, the module offers a noise figure of 7 dB typ., an output 1 dB compression point of +23 dBm typ., and an output third-order intercept point of +32 dBm typ. The RF input and output use 50 Ω SMA connectors.

Each hot-swappable amplifier occupies one chassis slot. Local and remote control are provided through the selected GENUS chassis, with supported interfaces including the front-panel touchscreen, Ethernet, SNMP, and HTTPS web access.
