The ADF5904 has fixed gain of 22dB and noise figure of 10dB and this is for the full ADF5904 signal chain, it is not broken up into individual blocks.
Our SA noise floor is -117dBm/10kHz.
In the testup HMC752 input is terminated. Its output is connnected to ADF5904. We are interested to measure noise floor of the HMC752+ADF5904 chain at IF=500kHz.
For converting the differential output of ADF5904 to…
The ADF5904 gain is fixed at 22dB.
Rm for the ADF5904 is 450 Ohms.
BiCMOS process same as ADF5904
Please checkout the ADF5904 datasheet (https://www.analog.com/media/en/technical-documentation/data-sheets/adf5904.pdf). The Receiver doesn't do an I/Q Demodulation. You only get In-phase data of all 4 channels out on the ADF5904 Rx_O pins…
ADF5904 baseband output spec is 10MHz
The attributes for the ADF5904 (within a parametric search on the ADI website) show that its primary function is IQ downconversion; however, isn't this just a differential output (for common-mode rejection) and not a true IQ output?
We are using the EV-RADAR-MMIC2 kit and we would like to know if the connectors are standard SMA or 3.5mm or something else?
I have looked for a figure of sensitivity in the data sheet, but I could not find it. My calculations show -90dBm, but that is assuming an SNR. Could you please specify SNR and sensitivity?
