Dear Sir/Madam,
My primary goal is to find the phase information of the received signal using a quadrature demodulation architecture receiver/transceiver. Therefore the signals I am most interested in are the I and Q signals at the output of the two down-conversion mixers since phase=arctan(Q/I) if my understanding is correct. From the data sheet of ADF7020, I learned that there might be several pins related to I and Q signals, i.e. MIX_Q, MIX_I, FILT_I and FILT_Q.
I wonder which pins I should use to fulfill my purpose here? Will I be able to obtain DC values for I and Q signals here?
Also, the datasheet indicates that these pins are high impedance pins and should be left open, how can I be able to monitor the signals from those pins?
Thank you so much in advance.
