Hi, I am student studying about radar circuit.
I found below circuits. they look like variable attenuat or controlled by voltage.
I don't know How it operate and How input signal is changed.
On Internet, there are many similar configuration and it is vector modulator.
However, it doesn't have wilkinson divider which should be included in vector modulator.
please explain below circuit in detail!
