BMCD17 DUAL CHANNEL LOW NOISE DOWN-CONVERTER
• • • •
VERY LOW PHASE NOISE LOW INTERMODULATION DISTORSION LOW POWER CONSUMPTION HIGH RELIABILITY
This down converter is intended for use in professional applications such as satellite earth stations. It has extremely low phase noise properties, making it possible to receive very weak signals close down to the thermal noise floor. Due to the weatherproof sealing, it can be used effectively in harsh environmental conditions.
