ETL Systems Alto ALT-G1R-S6-111 S-Band Redundant Variable Gain Amplifier 850–3150 MHz

The ETL Systems Alto ALT-G1R-S6-111 is an S-band redundant amplifier module operating from 850–3150 MHz. Designed for a compatible GENUS 1U chassis, it provides low noise, high linearity, adjustable gain, and positive slope compensation for satellite communications and RF distribution systems.

The published RF table specifies a nominal −4 to +45 dB gain range with 0.25 dB adjustment steps. Slope control provides 0–10 dB compensation with a pivot point at 3150 MHz, supporting correction of frequency-dependent cable loss.

At maximum gain, published performance includes a noise figure of 2.5 dB typ., output P1dB of +23 dBm typ., and OIP3 of +35 dBm typ. Gain flatness is ±2 dB across the full frequency range and ±0.2 dB over any 36 MHz in manual gain mode at zero slope.

Each hot-swappable amplifier occupies one slot in a compatible GENUS 1U chassis. The chassis platform supports redundant system arrangements, including 1+1, 2+1, and 4+2, with the appropriate amplifier modules and switching hardware. Local and remote monitoring and control are provided through the selected chassis.

This listing covers one ALT-G1R-S6-111 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 RF connector details, switching hardware, and configuration-specific performance when requesting a quotation.
