Luciano,
I will put this in OrCAD/CADENCE PSPICE over the weekend
and see what it looks like.

Hi all,
I can suggest a different solution I have tested to have some important
improvement. First, the lower phase shift sensitivity with the use of a low
pass filter in conjunction with two notch filters instead the high Q band pass
filter, second the unity gain to avoid a 13/20 dB
Luciano,
This looks very nice. However, the inductors are
custom made. It would be nice to have a
off the shelf parts solution so it can be made
easily.
Any ideas ?

I have my paper copy in front of me with the original article.

ARRL Author copyright matters. But I am willing to scan it.

Indeed it is. I designed a similar one using a quadrature hybrid
splitter and level 7 mixer, and it's almost scary how well it
works. It's as cute as a regenerative divide by two using a DBM.

I also appreciate the Wenzel circuit. Not seeing the other article, I might
guess that maybe it offers suppression of the original 5 MHz signal as a
benefit.
It seems to be the equivalent of a digital XOR circuit with one lead
delayed by 90 degrees.

Just a few days ago, I ordered parts to build a couple of the Wenzel 2-diode
doublers, described in the same article as your full-wave diode doubler,

go down to 5. It should.

Hi
The Wenzel doubler has a bit of “stuff” in the middle of the bridge. It’s tuned
a bit to give it best performance at a specific frequency. It’s not narrowband,
but it is not a 2:1 bandwidth.

Hi
In the “as wired” configuration, that looks more like a full wave doubler than
the full Wenzel tuned multiplier. You may be able to re-wire it for the full
circuit.

Personally, I'm lazy and like the Wenzel full wave rectifier
design with a nice BPF on the output to obtain a clean 10MHz.
The advantage of the multiplier circuit is that the signal straight
