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 using the shopping cart provided, or by sending an email to jim@w6pql.com . Payment can be made with your Paypal account (if you have one), or a credit card of your choice at checkout. Parts are usually sent Priority Mail the next business day. Postage is added at checkout, and can be as low as $7.50 within the U.S., and $15 U.S.D. International. The XRF amplifier kits are heavier, and postage is often higher on those; usually, several kits or parts can be sent in the same box for no additional postage. It can get a bit complex, but the checkout shipping calculator will figure it out for you.

Upgraded Multifunction Amplifier Control Board (V5) (sequencer + fan control + bias switch + VSWR switch)
This kit includes all parts shown here, plus a sensor (thermistor) for the fan controller, 3 panel-mount LEDs, and 2 spacers for mounting the board. The builder must supply the cooling fan, and a VSWR detector if those functions are to be used.

Lower-cost part for output power levels up to 50w |
23cm High-Power Coupler (Ro4003C)
This coupler is for those of us combining the outputs of larger amplifiers, even the bigger XRF-286, 2C39, or GS-15B high-power amplifiers. Made from thick (.060) Rogers R04003 low-loss substrate, it will handle more than 500W at the output. Requires a termination for the isolated port (like the 150w termination offered below). There is a VIDEO here showing how to connect this coupler. The hardware kit listed below contains an .040 aluminum spacer and the fasteners mentioned in the video. |
