About Posting a Comment

Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.

Author Name is a required field.

Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.

Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.

You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!

Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Good morning! Built a variation of this circuit using MPSH10 transistors (what I had) and a 50.000000 (yes, six zeros) FOX oscillator. Goal was to make a calibration source for an RTL2832 USB stick radio. Works great up to about 800 MHz where it starts to roll off in output, but was still quite usable up to 1 GHz.

Thanks much and and 73, Ben, KD5BYB

Arash,

Any specification on the harmonic power levels?

A canned 10 MHz TTL oscillator would almost do that out of the box, the square wave being quite harmonic rich, but of course the even harmonics would be much weaker than the odd ones.

Regards,

Alan

Hi, I saw your page and I think you can really help me. I need to design an engineered harmonic comb generator with fundamental frequency of 10 MHz and output signal level of 10 dBm . it should generate harmonics up to and including the 10th harmonic (100 Mhz ) . I have limited knowledge, and any help or design you suggest would be greatly appreciated ?
