This is built around Motorola's MRF559. C1 is is a 5 by 5 millimeter snip of PC board .2mm thick with the copper clad. Using very thin board will allow you to create small capacitors with a lot of Q. This cap is over 4 pF. L1 is approximately .4 nanohenries.
I will post the Smith Chart solution to this exercise at a latter date. I'll also address methods of determining device parameters using a slotted line. The line impedances are approximate. I built this a while back and have lost track of the original documentation.
By constructing an amplifier that exceeded the gain and efficiency expected from this device demonstrates that stripline does not have to be etched to achieve performance.
