product description
The BW-40 N is a high-performance attenuator, usable up to 100 Watt, offering an attenuation of
40 dB. Target areas of this attenuator are the measurement- and transmitter technology. The
guaranteed frequency range is DC - 4 GHz, the usable frequency range goes up to 5 GHz.
Connection norm is N, 1 x female, 1 x male. The attenuator can be expanded to a precise
50 Ohm load for a power of up to 100 Watt, just by screwing a KARN-connection in N norm.
