I have a simple oscillator that runs on +/-10V and sits inside a grounded metal housing. The oscillator puts out around 4W at 100MHz and I want to transfer that power as efficiently as possible, through a short coax, to another metal housing where there is an electrodeless lamp that runs on this RF.
I am considering connecting a 2.5 cm diameter coil between the output of the coax and ground and having another coil of maybe 2 turns (~180nH) as a parallel resonator with about 10pF capacitor across it. The two coils to be coxial and air-coupled.
The lamp sits coaxially within both coils.
Please see sketch here:
I have two questions:
(1) Does this arrangement sound feasible? And, if so, (2) can you suggest a simple capacitor and diode arrangement to measure reflected power so this can be minimized - an arrangement that doesn't draw of significant power itself.
Thanks for any input.
