Product Overview Mini-Circuits’ BW-20N100W+ is a 20 dB coaxial precision fixed attenuator providing high power handling of up to 100W over the DC to 6 GHz frequency range. This model supports many of high-power appli- cations requiring precise attenuation over a broad frequency range including high-power measurement, matching, instrumentation, and more. It provides good VSWR (1.25 typ.), outstanding attenuation flat- ness (±0.65 dB) and excellent thermal stability from -55 to 100˚C. It features rugged construction with N-male to N-female connectors and heat dissipation fins for efficient cooling.
