ETL Systems FN-D-C1L1-24426AC – Dual-Mode C-Band to L-Band Downconverter

ETL Systems FN-D-C1L1-24426AC – Dual-Mode C-Band to L-Band Downconverter

The ETL Systems Falcon FN-D-C1L1-24426AC is a dual-mode block downconverter that converts 3400–4200 MHz to 950–1750 MHz or 3700–4800 MHz to 950–2050 MHz. It provides nominal 0–35 dB variable conversion gain and 0–6 dB slope compensation for signal-level adjustment and frequency-dependent loss correction.

This hot-swappable, four-slot module uses dual-stage, non-inverting conversion and requires a compatible GENUS chassis. Local and remote monitoring and control are provided through the selected chassis.

Specifications apply to the standalone module. Refer to the manufacturer’s datasheet for complete phase-noise, spurious and redundant-system specifications. The reference-stability temperature range is not a complete module operating-temperature rating.

Compatibility and Ordering

Supports 1+1 redundancy with SWF-G1S-CX-111A or 2+1 redundancy with SWF-G1S-CX-117, together with the required additional converter modules. RF performance varies by configuration.

Specify the required frequency mode, connector configuration, chassis and redundancy arrangement when requesting a quotation. The RF specification table identifies the full part number as FN-D-C1L1-24426AC-S5S5.

The manufacturer identifies these specifications as preliminary, and a minimum order quantity applies. Confirm final specifications, minimum quantity and availability before ordering.

This listing covers one downconverter module. The GENUS chassis, redundancy switch, additional modules, external reference source, RF cables and accessories are sold separately unless included in the quoted configuration.
