ETL Systems TLT-U-L1L1-1001 L-Band Test Loop Translator 2025–2125 to 2200–2300 MHz

The ETL Systems TLT-U-L1L1-1001-S5S5 is an L-band-to-L-band test loop translator module for satellite communications test systems. It translates signals from 2025–2125 MHz to 2200–2300 MHz without spectral inversion.

The module provides 100 MHz instantaneous bandwidth and a synthesised local oscillator. Attenuation is adjustable from 0 to 30 dB in 0.25 dB steps, with a specified step tolerance of ±0.20 dB over the operating band. Conversion gain is −20 ±2 dB at the 0 dB attenuation setting.

Designed for a compatible GENUS 1U chassis, the module supports hot-swap replacement. Local touchscreen and remote Ethernet monitoring and control are provided through the compatible chassis platform.

The system supports an internal reference and an optional external 10 MHz reference with automatic detection. Confirm the required chassis, reference configuration, and module slot allocation when requesting a quotation.

This listing covers one TLT-U-L1L1-1001-S5S5 translator module. The GENUS chassis, external reference source, RF cables, and other accessories are sold separately unless included in the quoted configuration. Touchscreen, Ethernet, SNMP, web interface, and redundant power features depend on the selected chassis configuration.

The manufacturer’s V1.1 datasheet describes four-slot occupancy on the overview page and three-slot width in the specification table. Confirm the required slot allocation and chassis capacity before ordering. The reference stability temperature range is not a complete module operating-temperature specification.
