[time-nuts] Wenzel 100 MHz Oscillators (w/ EFC) available
Hello time-nuts, Please excuse the blatantly commercial announcement, I generally keep business matters off the list, but I have some Wenzel oscillators that may be of interest to time-nuts and wanted to give you first crack at them. These are Wenzel 500-06769 units, custom number for Harris used in microwave radios. Output is 100MHz at +20dBm. Supply input is +12 volts DC (about 500mA at start). EFC runs between 0.5V and 4.5V with positive coefficient and is about 335Hz/V. Unit is in standard 2 x 2 x .75 package. Output connector is female SMA. These would make great units for synthesizer and DDS projects. I don't have the ability to measure the phase noise, but should be relatively good as they were used at microwave frequencies in their past life. I'm asking $50 each for them and $7 (any quantity) Priority Mail shipping to U.S. addresses only. If you would like one (or more) please PayPal to pay...@rdrelectronics.com. I have attached a picture of one unit with the pinout.

I have a few of the 500-6769 parts here, and measured a couple of them awhile back: http://www.ke5fx.com/Wenzel_500_06769_PN.png Not a bad price at all. If a $2000 OCXO can achieve -140 dBc/Hz at 100 Hz and a $50 OCXO will do -117, that's almost 10 dB better than the expected 20*log10($2000 / $50) ratio. :) -- john, KE5FX Miles Design LLC ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

If it was a few dB better far out, it would outwenzel the Wenzel, phasenoise-wise. -117 is not a heroic deed. And the oven makes it easier to get along with a smaller tuning range, that helps a lot. Just forget these temperature corner cases that are major stumble stones in XO design. http://www.digikey.de/product-search/de?x=17y=16lang=desite=deKeyWords=cvhd950 regards, Gerhard ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

John Skip, as I am getting 5 such oscillators, I will open 2 or three (after measurements of the PN ) and apply some magic... To build something like this mechanically will be tough. The technology and circuit design will have changed a lot in 10 + years, so I will try. Opening the units may be the tough part. 73 de Ulrich x I have a few of the 500-6769 parts here, and measured a couple of them awhile back: http://www.ke5fx.com/Wenzel_500_06769_PN.png Not a bad price at all.
