Tunnel diode versus dual gate MOSFET - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

Would like to exchange your experience with tunnel diode, high stability oscillators. Lets say 400MHz to start with. It seems to me, they have much cleaner output and stability compared to bjt.

Tunnel diodes are an older technology that's harder to buy than BJTs. (Almost) no new devices have been introduced in the last decade. That's a good indicator that other approaches work better.
Check out Randy Rhea's book on oscillator design - he does a good job of providing analysis tools for oscillator noise.
