I am hoping this will allow me to forgo the need for the beads and coax as the output on the Spartan is 75 Ohm.

The CM 0064DSB has a regular ferrite 300:75 Ohm balun at its input.
The core and windings are seen in the lower right of this image (near input terminals).
Could be CM used a slightly better core than used in most commercial baluns. However, the balun has loss.
Removed the core and windings, replaced with half-wave loop saw signal about 1-2 dB strength improvement.

No offense Sev, the post was quick and for a while was thinking about Bob's earlier posts.
