ETL Systems TLT-D-KXL1-1008 Ku-Band to L-Band Test Loop Translator 12.75–14.5 GHz to 950–1950 MHz

ETL Systems TLT-D-KXL1-1008 Ku-Band to L-Band Test Loop Translator 12.75–14.5 GHz to 950–1950 MHz

The ETL Systems TLT-D-KXL1-1008-S5S5 is a Ku-band-to-L-band test loop translator module for satellite communications test systems. Two conversion modes cover input frequencies from 12.75–14.5 GHz, translating the selected 1 GHz input band to 950–1950 MHz without spectral inversion.

Mode 1 accepts 12.75–13.75 GHz with an 11.80 GHz LO. Mode 2 accepts 13.5–14.5 GHz with a 12.55 GHz LO. Each mode provides 1 GHz instantaneous bandwidth.

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-D-KXL1-1008-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 12.75–14.5 GHz input coverage is provided through two conversion modes, rather than as simultaneous instantaneous bandwidth. The V1.0 datasheet lists two LO frequencies but does not specify an LO tuning step size or maximum module count per chassis. The reference stability temperature range is not a complete module operating-temperature specification. Confirm RF connector details, chassis capacity, and the required reference configuration when requesting a quotation.
