ETL Systems Alto ALT-G1R-S3-101 Extended L-Band Redundant Amplifier 850–2450 MHz

The ETL Systems Alto ALT-G1R-S3-101 is an extended L-band redundant amplifier module operating from 850–2450 MHz. Designed for a compatible GENUS 1U chassis, it provides low noise, high linearity, variable gain, and slope control for satellite communications and RF distribution systems.

The module supports 1:1, 2+1, and 4+2 redundancy when combined with the appropriate ETL switch hardware and amplifier modules. Gain range, slope compensation, and RF performance depend on the selected redundant configuration.

In the specified 1:1 configuration with the SWF-G1R-SX-101 switch, nominal gain is adjustable from −7 to +42 dB in 0.25 dB steps. Slope compensation provides 0–6 dB adjustment with a pivot point at 2450 MHz. At maximum gain, this configuration provides a noise figure of 5 dB typ., output P1dB of +19 dBm typ., and OIP3 of +31 dBm typ.

Each hot-swappable amplifier module occupies one chassis slot. Local touchscreen and remote monitoring and control are provided through the selected GENUS chassis.

This listing covers one ALT-G1R-S3-101 amplifier module. The GENUS chassis, additional amplifier modules, redundancy switch, RF cables, and other accessories are sold separately unless included in the quoted configuration. No LNB powering is provided. Indoor operation requires a compatible parent GENUS chassis. Confirm the required redundancy arrangement and configuration-specific RF performance when requesting a quotation.
