I have an LDMOS amplifier. I am testing it using a power meter. When the second port of the power meter is connected to standard 50 ohm termination, everything goes well.
However when I connect it to my load which shows 50 ohm on VNA, the Gate to Source Voltage increases and there is an abrupt increase in output power. I am unable find out the reason. Any help will be appreciated.
