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.

Note: This product is a kit which may involve building the product by selecting individual components, soldering them to the circuit board, winding toroids, installing LEDs and displays, calibrating circuits to meet specified performance levels.

    FAQ

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

    A: No but we do have builders for hire.  Visit Support for our Builders Resources page for a list of Builders for Hire.

    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.
