it is for building a frequency multiplier circuit with a step recovery diode(srd)hcseu said:what's the name of the application?
when you say 'doing a modern design' what do you mean exactly?biff44 said:Yep, thats the one! It is a shame in this modern age of CAD RF software suites, that no one has properly modeled the SRD diode yet! What the heck are they waiting for?
This app note is great for designing a comb generator, and it works exactly as described. It is also great if you want to build something like a X10 multiplier.
Where this paper takes a left turn from reality is when you are designing a X2 to X4 multiplier. By following this paper's method, you will get maybe 10-30% efficiency. By doing a modern design, using the correct terminating impedances on the idler frequencies, you can get 80% for a X2, for instance.
