results of my MHL21336 amp
Great! Thank you for sharing.
I have a module I have not built yet so nice to get some outside validation that it works well.
I will use a 1.6mm PCB and manually cut 50ohm stripline with a scalpel to my SMA edge connectors as the module seems to be made to have a 1.6mm PCB between its pins and the ground-plate.
How much heat is it generating for you?
I guess your big heat-sink is little bit overkill at 0.4W ?
