Follow

The difference between the 150-A, 150-SA, and 150-WA attenuators is style of heatsink, location of input and output connectors and frequency range. 

  • 150-SA and 150-WA have the connectors in-line, or straight through the heatsink. 
  • 150-A attenuator has the input and output connector on the same side of the heatsink. 
  • 150-A attenuator has a frequency range from DC to 3GHz where the 150-SA and 150-WA are DC to 2.4GHz.

Outline drawings of each version are attached so you can see the differences in configuration and the specifications.
