A coaxial attenuator. Here’s a breakdown of what each part of the description typically means:

1. DC-6 GHz: This indicates the frequency range over which the attenuator operates effectively. In this case, it’s suitable for frequencies from direct current (DC) up to 6 gigahertz (GHz).

2. 30 dB: This is the level of attenuation provided by the attenuator. It means the attenuator will reduce the signal strength by 30 decibels.

3. 10 W: This denotes the maximum power handling capability of the attenuator. It can handle up to 10 watts of power without damage.

4. Female Connector: This specifies the type of connector on the attenuator. “Female” means it has a receptacle that accepts a male connector.

5. RF: Stands for Radio Frequency, indicating the type of signal the attenuator is designed to handle.
