ETL Systems Alto ALT-G2S-KX-147 5–18 GHz Variable Gain Low Noise Amplifier Module

ETL Systems Alto ALT-G2S-KX-147 5–18 GHz Variable Gain Low Noise Amplifier Module

The ETL Systems Alto ALT-G2S-KX-147-K5K5 is a wideband, low noise RF amplifier module operating from 5–18 GHz. Designed for a compatible GENUS 2U chassis, it combines adjustable gain with high linearity for RF signal conditioning and level balancing.

The amplifier provides nominal gain adjustment from 0–26 dB in 1 dB steps. At maximum gain, it offers a noise figure of 3.5 dB typ. and an output third-order intercept point of +33 dBm typ. Its 50 Ω 2.92 mm female input and output connectors support microwave signal connections.

Each hot-swappable 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.

Optional 1+1 amplifier redundancy can be implemented with additional amplifier and switching hardware plus external cabling. Performance depends on the complete redundant configuration.
