Teflon circuit board has better characteristics at microwave frequencies so use that instead if you can find it. Its part number is PC44-ND for 3 x 4.5 inches and costs $3.23.
The Injectorall circuit board from Digi-Key is perfect. You'll want to pick up some quality 1/32 inch, double-sided, one ounce oz copper clad FR-4 circuit board. You can order these for around $2 each from Newark Electronics or Allied Electronics. Next, read the data sheet for the Intersil RF1K49093 8-pin PSOP power MOSFET. You can order these for around $8 each from Arrow Electronics or Allied Electronics. Next, read the data sheet for the Intersil HFA3424 2.4 GHz - 2.5 GHz low noise amplifier.

To use PostScript under Window$, you'll need to install the Ghostscript & Ghostview packages.
Most schematics are in their native Xcircuit PostScript format for ease of printing and modification. If you're too stupid to figure that out, then please don't build these.Īdaptation to wireless network cards other than the Proxim Symphony should be trivial. If you don't need to have the receiver amplifier (due to excess local noise/intermodulation or loss coax loss), just replace it with a stripline jumper. When done wrong, your stuck listening to shortwave broadcast stations in Yugoslavia. To do this, attenuate the RF input power slightly. If adapting for use on direct sequence spread spectrum systems, you'll want to lower the overall P1dB (+28 dBm or so) to keep the RF power amplifier in its linear region.
The final RF power output of this amplifier will be around +31 dBm (1.3 watts) and the receive gain is around 16 dB (with a 2 dB noise figure). Also, instead of a complicated RF sensing transmit/receive switch, a logic level indication of transmit is sent to the amplifier through a length of low cost coaxial cable. The cost is reduced by using readily available materials and components. Bi-directional means you can mount the amplifier at the antenna to help overcome any cable loss, and the amplifier will automatically switch between receive and transmit modes.
