ETL Systems TLT-U-K1L1-1010 L-Band to Ku-Band Test Loop Translator 950–2000 MHz to 10.7–12.75 GHz

ETL Systems TLT-U-K1L1-1010 L-Band to Ku-Band Test Loop Translator 950–2000 MHz to 10.7–12.75 GHz

The ETL Systems TLT-U-K1L1-1010-S5S5 is an L-band-to-Ku-band test loop translator module for satellite communications test systems. It accepts 950–2000 MHz signals and translates them to one of two Ku-band output ranges without spectral inversion.

Mode 1 provides 10.7–11.75 GHz output, while Mode 2 provides 11.7–12.75 GHz output. Each mode supports 1.05 GHz instantaneous bandwidth, covering the full specified L-band input range.

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 0 ±3 dB at the 0 dB attenuation setting. A mute function provides at least 80 dB suppression.

The hot-swappable module occupies four slots in a compatible GENUS 1U chassis. Local touchscreen and remote monitoring and control are provided through the compatible chassis platform.

This listing covers one TLT-U-K1L1-1010-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 full 10.7–12.75 GHz output coverage is provided through two conversion modes, rather than as simultaneous instantaneous bandwidth. The V1.1 datasheet does not specify LO tuning steps or maximum module count per chassis. Its external-reference row places “10 MHz” and “automatic detection” under separate mode labels; confirm the reference arrangement for the required configuration. The reference stability temperature range is not a complete module operating-temperature specification. Confirm RF connector details and chassis capacity when requesting a quotation.
