Some of the projects listed on this site produced requests for PC
boards and other parts, so I took the time to make up some board level kits for
the more popular projects.
Instructions on assembling and use are contained in the articles on this
site, as well as close-up component layout pictures to aid in assembly.
Surface-mount parts are used throughout, so it is helpful to have some
experience in working with them. There is a
video here showing some of the
techniques used in working with these components.
You can order any of the items listed here by sending an email to:

Paypal is the preferred payment method; personal check or money order are also
OK. Add $5 postage for the U.S. or Canada, $10 USD for international. Several kits or parts
can be sent for no additional postage.

23cm PTFE High-Power Coupler

For those of us combining the outputs of amplifiers, even the bigger XRF-286, 2C39, or GS-15B
high-power amplifiers. This one is made from thicker (.062) PTFE
low-loss substrate, and will handle more than
500W at the output. Requires a stripline termination for
the isolated port (the 100w termination is recommended for output levels
over 150w). |
