Can anyone direct me to an amplifier with:
1. High reverse isolation
(over 40 dB). Note: the spec of interest
is *reverse* isolation, not port to port
isolation in a distribution amplifier.
2. Low phase noise
(less than -100 dBc/Hz at 1 Hz offset)
3. Works at 200 MHz
The Q-Bit QBH-1401PM seems promising...if I
can get one.
If necessary I will build the amplifier
if I can get a known good schematic to follow,
but prefer to buy one.
Thanks in advance.
