Hello everyone,
I am new to this list, happened across it while searching on distribution
amplifiers.
I need to design a 10 MHz isolation/distribution amplifier with two outputs for
a high-vibration wide temperature range environment. I was considering using a
design based on the NIST article 'A new 5 and 10 MHz distribution amp', most
likely the third incarnation, as I cannot tolerate modulation of the signal via
the transformer.
I have looked at the work by Gerhard Hoffman, which is impressive. However,
the transformer remains. I should mention I am also limited to 15V power
supply, and need to output into 50 ohms at 10 dBm. Ideally DC current will be
minimized, preferably 20 - 30 mA per channel. I can generate a negative power
supply if necessary, but would prefer not to.
If anybody can offer tips so I don't undertake to reinvent the wheel, it would
be appreciated.
Thanks in advance,
- Lifespeed
