Regarding ddistribution
divider/amplifier for 10 MHz in the past I have talked to others on this
subject and the
consensus was that the frequency response of the
amplifier must be grater than 10 times ?that of the reference frequency to
prevent distortion and lag
we ended up using transistors that where good for
450 MHz for a 10 MHz reference
?

Distribution divider/amplifier for 10MHz GPSDO
?
?
Hello
group. I`m intending to distribute, via 50 Ohm coax, frequency reference
signals to my test equipment in my test bay [no relation to eBay, except that
most of the equipment came from there]. I`ll be using RG58/U coax, and 50 ohm
terminations, with the highest reasonable signal level reticulated. Given that
the name of the game seems to be to avoid any severe reduction in SNR of the
10MHz signal comming out of the GPSDO, by the logic dividers, and impedance
lowering buffer amplifiers, what considerations should be made regarding the
choice of logic families, and transistors to be used? The frequencies required
by the test equipment vary from 500kHz to 10MHz, and amplitudes from 100mV P-P
sinewave, to 5V peak squarewave. How good must the PSU be to stop the rot
getting worse, and is 1/f noise in the active devices important? Your thoughts
will be appreciated.
P.S.: How
accurate is the Trimble Thunderbolt for this
application?..............................................Thankyou,............Don
Collie.
