Mini-Circuits Attenuators BW-40N100W+

The BW-40N100W+ is a coaxial fixed attenuator designed for use in RF applications, featuring a frequency range from DC to 4000 MHz. It provides a nominal attenuation of 40 dB with a maximum power rating of 100W at 25¬8C, which derates to 50W at 100¬8C. The device is bi-directional and includes N-Male and N-Female connectors, ensuring compatibility with standard RF systems. This attenuator exhibits excellent voltage standing wave ratio (VSWR) performance, with values of 1.15:1 to 1.40:1 across its frequency range. The temperature coefficient for attenuation is specified at 0.0004 dB/dB/¬8C, indicating stable performance over varying temperatures. The operating and storage temperature range is from -55¬8C to 100¬8C, with a maximum of 85¬8C for unmated connectors. The BW-40N100W+ is RoHS compliant, making it suitable for environmentally conscious projects. It is ideal for applications such as instrumentation and test setups where precise signal attenuation is required.
