Hot Carrier or Shottky(?) diode recommendations?

[W6CUX]

A very good replacement for the 1N191 is the hp5082-2800 
which is now available from several manufacturers as the 
1N5711.

Mouser has 57,000 Vishay 1N5711 in stock for $0.13 each in 
small quantities.

 See:    http://www.mouser.com/catalog/624/334.pdf

The HP/Agilent data sheet is at:
  http://www.alltronics.com/download/22S002.pdf

The 1N5711 works very well in the SB/HW balanced modulators 
and as RF detectors in SWR bridges and output circuits.

Can someone recommend a very good upgrade to the usual 1N191 
diode Heath
used in detectors and ring modulators? ........
 I believe what I want is a so called 'Hot Carrier Diode' 
(Schottky?)........
 And a source would be appreciated. ......

Terry, Rob, et al,
I replaced the diodes in my HW100 with Schottky diodes quite
some time ago and it made a definite improvement in S/N
ratio. The receiver is quieter for sure.  I bought them from
Brad Thompson AA1IP at email Brad.Thompson at valley.net  which
is the last address I have.

The part number is for the HP 5082-2800 and he charged me $1
including shipping for a handfull of them plus a couple of
other ones. Even if his price is more, it is well worth it.

Good luck and 73, Dick KF4NS
