Diode tripler identify magazine source?

Hello, I would like to identify the magazine and issue of this diode tripler

(found at link below)

I think it is the ham radio magazine but what issue?

Also what kind of max output power would you expect out of this?

if you really tweaked it up, maybe a 10 dB conversion loss. but it is not an optimal circuit--there is no idler frequency tuning for the 2nd harmonic

I don't think you need any more other data. The picture has all the information you need to build the circuit.
L1 and C1 tuned for input matching at 422MHz and C2 and C3 tuned at 1267MHz. C4 gives the bandwidth.
R1 help to bias the diode for various input levels.

Why not drop a e-mail to Yo3DAC?

Article is published in Ham Radio september 1974 1296MHz SSB Transceiver page 8. This is a source of many articles or scheme that VA3IUL used.

Yes thank you I have found it.
The output is 40mW with 500mW input.
Thanks a lot!
