ETL Systems FN-D-L1F2-24404AA – 850–3150 MHz to 70/140 MHz Downconverter

The ETL Systems Falcon FN-D-L1F2-24404AA converts 850–3150 MHz signals to 70 MHz or 140 MHz IF, with 1 kHz frequency tuning and nominal 5–35 dB variable conversion gain. This hot-swappable, four-slot module uses dual-stage, non-inverting conversion and requires a compatible GENUS chassis for operation, local control and remote monitoring.
