Mini-Circuits’ BW-40N250W+ is a 40 dB coaxial precision fixed unidirectional attenuator providing high power handling of up to 250W over the DC to 8 GHz frequency range. This model supports many of high-power applications requiring precise attenuation over a broad frequency range including high-power measurement, instrumentation, and more. It provides excellent VSWR (1.11 typ.), outstanding attenuation flatness (±0.7 dB) and excellent thermal stability from -55 to 125˚C. It features rugged construction with N-male to N-female connectors and heat dissipation fins for efficient cooling.
