Appended to bottom of:
is a Q-Meter prototype schematic proposal.
For greatest accuracy, RF to injection transformer should have low
impedance, proposing an AD8055 direct connection.
A requirement is a AWG with calibrated output for RF In.
Assumption: "RF Voltmeter Prototype" will behave appropriately when
placed onto a proper PWB. Suggestion J111 or J112 input FET.
Can envision two PWBs. One large with all components. Second smaller,
mezzanine board, above the 50:1 injection transformer, for L and C
connection points.
