Dean's Tiny Tia -- Hardcore Homebrewing


 
Hi guys,

I've been on kind of a building hiatus due to various issues, but after seeing the work being done with the termination insensitive amplifiers I had to start noodling again.....as Pete would say.  Well I have decided to build a TIA (ZIA according to Pete) SSB transceiver.  I've decided to homebrew everything including the DBM, crystal filter, and even the Si5351 module.  As I wait for more parts to come in, I wanted to show the 2 TIA amps and crystal filter assembly I've built.  I've included a screenshot of the pass band response through the amps and the crystal filter.  It looks the same in both directions and everything fits into an area of 2 x 2.5 inches.  With the space left on the board, I hope to be able to put my SBL-1 clones on as well.  I follow up as I get more completed.
