The Bracke BM10016, BM10083 and BM10085 series consist of fixed coaxial attenuators designed for 50-ohm RF signal paths with a 7/16 DIN interface. All listed models cover a frequency range from DC to 7.5 GHz.
The three series primarily differ in their power ratings. The BM10016 series is rated at 5 W, the BM10083 series at 10 W and the BM10085 series at 25 W. Depending on the series and reference, fixed attenuation values from 1 to 40 dB are listed.
Advantages
- Three power classes: Choice of 5, 10 or 25 W according to the power level of the RF signal path.
- Frequency range up to 7.5 GHz: For broadband RF applications from DC to 7.5 GHz.
- Fixed attenuation values: Defined signal-level reduction for measurement, test and system applications.
- 50-ohm system impedance: For corresponding RF components, instruments and system environments.
- 7/16 DIN interface: For coaxial RF signal paths using this connector type.
- Consistent maximum VSWR: 1.45:1 for all listed versions.

Additional information
The appropriate series is selected according to the required power rating of 5, 10 or 25 W. Within each series, the reference is selected according to the required attenuation value and permitted attenuation deviation. EMCO supports the technical selection and positioning of the appropriate attenuator within the complete RF measurement or system chain.
