Fixed RF attenuators – TNC, up to 18 GHz and 5 W: BM10019 / BM10080 / BM10082 | Bracke Manufacturing

The Bracke BM10019, BM10080 and BM10082 series consist of fixed coaxial RF attenuators for 50-ohm signal paths with TNC interfaces. They provide defined signal-level reduction in RF and microwave measurement chains.

The BM10019 series covers a frequency range from DC to 2.5 GHz and has a specified power rating of 2 W. The BM10080 series extends the frequency range to DC to 18 GHz with the same power rating and is described in the provided information as a TNC male version. The BM10082 series also operates from DC to 18 GHz and provides a higher power rating of 5 W.

Advantages

• Three product series: Selection according to the required frequency range and power rating.
• Frequency ranges up to 18 GHz: Versions for RF and microwave applications.
• Power ratings of 2 or 5 W: Selection according to the signal-path power level.
• Fixed attenuation values: Model-dependent selection from 1 to 30 dB.
• 50-ohm system impedance: For compatible coaxial instruments, components and system chains.
• TNC interface: For RF signal paths using this coaxial connector type.

Additional information

The appropriate series is selected according to the maximum frequency range, required power rating and required TNC configuration. Within each series, the reference is selected according to the required attenuation value and permitted attenuation deviation. EMCO supports the technical product selection and integration of the attenuator into the complete RF or microwave measurement chain.
