Your easiest solution is to buy a used dual band router...

The inherent problem is that circuits that operate at such frequencies are not built with "lumped" components like circuits at lower frequencies. At these frequencies you use "distributed" components because the dimensions of the circuit are the same order of magnitude as the wavelength of the signals.

\(\lambda f\; =\; c\)
\(\lambda\; =\; \frac{3\times 10^{8}}{5\times 10^{9}}\;=\;0.06\;\text Meters\math\;=\;6\;\text cm\)

How you translate a schematic into a working circuit makes all the difference between working and a pile of scrap.

My small experience is that Mini-Circuits prices are reasonable considering they have done a lot of the hard design for you.

The traditional way was to feed the original frequency into an amplifier tuned to some not too distant harmonic of the original frequency - papabravo's post is the first paragraph of the bible you need to read before plugging the iron in.

There could well be state of the art PLL chips that make it all easy.

There are two ways to use them:

1. Design a PCB to mount them with appropriate connectors, control and power.
2. Manhattan style "dead bug" construction.

Either one will definitely challenge your abilities.

This give me a clue where to start thanks papabravo
