To specify the required attenuation value, replace the 'X' in the model with the attenuation value in dB.
   Example: MA-505/6N-6 specifies a 6 dB, MA-505, 6.0 GHz attenuator with type N male/female connectors
                     MA-525/20D7-2 specifies an 20 dB, MA-525, 6.0 GHz attenuator with 7/16 DIN male/female connectors.
* Units with 7/16 DIN connectors can be provided with a frequency range of DC to 7.5 GHz. Consult factory.
† Accuracy specified is at the highest rated frequency.  Accuracy is typically improved at lower operating frequencies.
