Gerhard - I would like to make the board if you could make the layout available. I don't have Altium, so would need the artwork to be able to toner transfer the board. Is it available?

Hi Time-Nuts - FWIW, the is a 30 day free trial of Altium Designer at http://www.altium.com/free-trial?gclid=CKnpkaux38QCFQotaQodoaYAWQ The download requires a company name and email address. I for one, would like at least one of each of Gerhard's boards. Would anybody like to volunteer to create 10-20 boards and sell them? If people are interested in boards, they can pm me at j...@pcsupportsolutions.com And I will make a list and post it. In your email, provide your name and email address and how many multiplier boards and how many low noise 220pV/sqrtHz preamp boards? I have no time to do any more than that. Is this worth being a TAPR project?

Re: [time-nuts] Frequency doubler 5/10 and distribution amplifier for Lucent KS-24361
Hi Based on the phase noise on the 15 MHz output, I would *guess* that the 5 MHz OCXO has a floor in the vicinity of -160 dbc / Hz. That would be correct per the MTI spec sheet. It also would make sense based on your phase noise plots. Close in ( around 200 Hz) your multiplier and amp are doing a better job than the stock 15 MHz tripler and buffer. They have a lot of buffer amps in their 15 MHz chain, so who knows where the issue is in the stock design.

Re: [time-nuts] Frequency doubler 5/10 and distribution amplifier for Lucent KS-24361
Hi So is any of the rest of the family still speaking to you? :) That’s a lot of work. Very nicely done and documented !! Phase noise or ADEV would be well worth checking out. I see no reason why they would be a problem, but one never knows until the test is run. — I would suggest *some* resistance to ground on the outputs of the distribution amp. Without any R, you can get into ESD issues when you connect a cable. Is it a big deal - not really.
