Attenuators are passive devices which absorb energy from an RF signal, reducing its power level while still preserving the signal\'s wave-shape. The M3933/30-18S attenuator is a broadband, high power, mechanically-variable attenuator. It is designed for use with transmitters in the broadcast, cellular, and microwave frequency bands.

The M3933/30-18S attenuator features a wide range of power handling capabilities, from 1 W to 30 W, and 18 dB of maximum attenuation. The attenuator utilizes an internal rotary switch which is driven by a knob or handle to vary the attenuation from 0 to 18 dB. The resistance and inductance of the attenuator are connected in series with the RF signal path in order to absorb and dissipate energy from the RF signal.

The attenuators can be used in a variety of applications such as signal level adjustment in test instrumentation, impedance matching, or pulse shaping. The M3933/30-18S attenuator is specifically designed for use with transmitters in the broadcast, cellular, and microwave frequency bands, where it can be used to reduce the power of the signal.

The working principle of the M3933/30-18S attenuator is based on impedance matching. The device is designed so that the resistance and inductance of the attenuator have an effect on the power of the RF signal. The resistive elements absorb the energy of the RF signal, while the inductive elements dissipate the energy.

The resistance and inductance of the attenuator are varied by the rotary switch, which is driven by a knob or handle. The switch controls the amount of attenuation applied to the RF signal. As the knob or handle is turned, the resistance and inductance of the attenuator change, reducing the power of the signal.

The M3933/30-18S attenuator is a high power, mechanically-variable attenuator designed for use with transmitters in the broadcast, cellular, and microwave frequency bands. It offers a wide range of power handling capabilities, from 1 W to 30 W, and 18 dB of max attenuation. The device utilizes an internal rotary switch to adjust the resistance and inductance of the attenuator, allowing for precise signal level adjustment. The attenuator’s working principle is based on impedance matching which enables the reduction of the power of the signal.
