Please add a 3K3 ohms resistor just behind the 1µ and 100 pf input capacitors. Otherwise the two protection diodes can distort TTL signals (at certain frequencies) to a level where the output is not reliable anymore.
The General Electronics topic is intended for posts from people seeking help.
This is a helpful post but you are not asking for help. Your post would probably be better in the Exhibition /Gallery, even though that topic is really overkill for this post. Ideally, the forum should have a topic that covers everything in between but not necessarily Exhibition posts. Perhaps a topic called "General Electronics Miscellaneous suggestions and tips" ?
It seems like overkill for only 20MHz. There are a number of MMIC wideband amplifiers that are good to 1GHz, depending on board layout. Around $10 give or take. Or on eBay, 5 for $10 give or take.

Otherwise the amplifier works perfectly.
Those input diodes will be fried without series resistance too! I'd suggest 220 ohms so there's
less reflection and better damping.
