ETL Systems FN-D-C1L1-24426AA – C-Band to 1150–2150 MHz Block Downconverter

ETL Systems FN-D-C1L1-24426AA – C-Band to 1150–2150 MHz Block Downconverter

The ETL Systems Falcon FN-D-C1L1-24426AA converts one of three user-selectable C-band input ranges to 1150–2150 MHz L-band output. 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 input-frequency mode, connectors, chassis and redundancy arrangement when requesting a quotation. The full ordering number includes a configuration suffix: FN-D-C1L1-24426AA-XXXX.

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.
