OVERVIEW

The AT1 features an unusually high upper power limit of 2 watts, making it ideal for many applications where attenuators with a lower power rating cannot be used such as at the output of a QRP transmitter for QRPp experimentation. The AT1 step attenuator is designed to be used as a standalone unit. Optionally, it may be built into existing equipment or an enclosure of your choice.

    FAQ

    Q: Does Elecraft sell a factory built version of the AT1?

    A: No but we do have builders for hire.  Please contact sales@elecraft.com for more details.

    Q: How easy is the AT1 to build?

    A:  All of our Mini-Modules kits are straightforward, one night projects. The kits are easy to assemble, featuring our "no-wires" construction. They are also a great way to get back into the swing of building and to improve your building skills.  All of our Mini-modules have no user installed surface-mount technology, so they are an ideal project for first-time builders.
