Building an AD8307 RF Power Meter

Power Meter shown measuring the output signal of a Rig Expert Analyser (-10dBm )  at 100mHz
VSWR 1.08 indicates a nice 50 ohm input impedance.


Connected to a home brew 40dB tap to allow higher power measurements,
no signal noise floor is -74dBm…near enough for a backyard project.
AD8307 power head, this assembly is enclosed in a brass screen to improve noise figures.
