I've been wanting to do a PIN diode u/g for my DX-394's preselector
bandswitching for a couple of years since reading the Kiwa article. But I
wanted surface mount to directly replace the existing diodes. I think I
have found them for the three SW bands - Infineon BAR64-03W PIN Diodes in
a SOD-323 package with a typical charge carrier lifetime of 1.55us.

Pete, do these look like a good alternative to the axial leaded 1N5767?


Those diodes should be fine.

Still looking for something for the MW and LW bands in a dual diode
SOT-343 package to replace the DA277's:

Unitrode is another manufacturer to try......................they may have a
suitable replacement.
