The boards for the DMTD mixer board arrived!

I'll be populating and testing and will post updates.

Cheers!

What are all those holes for??  Seem too big to be vias.

 >:D ;D

tkamiya:
Will you share the design of the circuit?  I've been wanting to do this myself.

5065AGuru:
Yes I will be sharing the schematic/parts list/and expressPCB file.
Once assembled I'll be testing it and determining the noise floor.
I'll share some plots taken with it and some pointers on how to get the best results from the particular frequency counter you use with it.
I'm also in the process of designing a counter to go along with it so you don't have to tie up your fancy counter.

Just populated the front end and mixers and have good signals out of the mixers. Will be doing the rest of the board soon. I need to breadboard the op amp portion first so I can determine what bandwidth I want to use.

Cheers,

Corby

Looks awesome Corby!  You know I'm all over this!  I'm so psyched after the bad experience with the TURN Dynamic Systems DMTD I bought!

Best Regards,

Bill
