ETL Systems Alto ALT-G1R-L1-105 L-Band Redundant Amplifier Module 850–2150 MHz

ETL Systems Alto ALT-G1R-L1-105 L-Band Redundant Amplifier Module 850–2150 MHz

The ETL Systems Alto ALT-G1R-L1-105 is an L-band amplifier module designed for the GENUS 1U redundant chassis range. Operating from 850–2150 MHz, it combines low noise, high linearity, variable gain, and adjustable slope for RF signal conditioning in redundant amplifier systems.

The module supports 1:1 redundancy configurations using compatible switching hardware. With the SWF-G1R-SX-101 switch, the specified configuration provides nominal gain from −2 to +28 dB and 0–6 dB slope control. With the SWF-G1R-SX-114 switch, the specified gain range is −5 to +25 dB with 0–5 dB slope control.

Fine gain adjustment in nominal 0.25 dB steps supports signal-level balancing. Slope control pivots at 2150 MHz to help compensate for frequency-dependent signal loss. RF connections use 50 Ω SMA ports.

Each hot-swappable amplifier module 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.
