Fixed RF attenuators – 10 W, DC to 40 GHz: BM10098 series | Bracke Manufacturing
Bracke BM10098 fixed 50-ohm attenuators with 2.92 mm interfaces, a 10 W power rating, DC to 40 GHz operation and attenuation values from 3 to 40 dB.
The Bracke BM10098 series consists of fixed coaxial 50-ohm attenuators with a 2.92 mm interface. The models cover a continuous frequency range from DC to 40 GHz and are rated for an RF power of 10 W.
The series is available with fixed attenuation values of 3, 6, 10, 20, 30 and 40 dB. All versions have a maximum VSWR of 1.35:1. Attenuation accuracy ranges from ±0.8 to ±1.2 dB, depending on the selected model.
Advantages
- Broad frequency coverage: Operation from DC to 40 GHz for RF and microwave signal paths.
- 10 W power rating: Common specified RF power across all models in the series.
- Six fixed attenuation values: Choice of 3, 6, 10, 20, 30 or 40 dB.
- Defined attenuation accuracy: Model-specific accuracy values from ±0.8 to ±1.2 dB.
- Consistent VSWR: Maximum VSWR of 1.35:1 for every version.
- 2.92 mm interface: For compatible coaxial RF and microwave measurement chains up to 40 GHz.
