ETL Systems Alto ALT-G2S-L1-130 L-Band High Linearity Variable Gain Amplifier 850–2150 MHz

ETL Systems Alto ALT-G2S-L1-130 L-Band High Linearity Variable Gain Amplifier 850–2150 MHz

The ETL Systems Alto ALT-G2S-L1-130 is a high linearity L-band amplifier module operating from 850–2150 MHz. Designed for a compatible GENUS 2U chassis, it provides variable gain and adjustable slope for RF signal conditioning, level balancing, and frequency-response compensation.

The amplifier offers nominal gain adjustment from 15–45 dB in fine 0.25 dB steps. Slope control provides 0–8 dB adjustment with a pivot point at 2150 MHz. Manual gain and automatic output-level control modes support different signal-management requirements.

Three operating modes allow the amplifier’s performance to suit the application. Power Mode adjusts input attenuation to prioritize linearity as gain is reduced. Noise Mode adjusts output attenuation to prioritize noise figure, with reduced linearity at lower gain. Compromise Mode distributes attenuation equally between the input and output.

At maximum gain, the amplifier provides a noise figure of 4 dB typ. and an output third-order intercept point of +42 dBm typ. Each hot-swappable module occupies one slot in a compatible GENUS 2U chassis, with local and remote control through the selected chassis platform.

This listing covers one ALT-G2S-L1-130 amplifier module. The GENUS chassis, 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. Output compression performance varies with gain and operating mode; confirm the required operating point and connector configuration when requesting a quotation.
