126, UG-570 AD9361 Reference Manual | Page 126 of 128 Rx LO FREQUENCY DEVIATIONS DUE TO POWER SUPPLY TRANSIENTS The AD9361 is a transceiver that can operate in TDD or in FDD mode. In FDD mode, there is a need to dynamically change the transmit power when the receivers are on and …

12, UG-570 AD9361 Reference Manual | Page 12 of 128 RF DC OFFSET CALIBRATION The RF DC offset calibration should be run once during initialization, or potentially when moving to a new carrier frequency that is more than 100 MHz away from the previous carrier frequency. This ca…

36, UG-570 AD9361 Reference Manual | Page 36 of 128 GAIN CONTROL THRESHOLD DETECTORS The AD9361 uses detectors to determine if the received signal is overloading a particular block or if the signal has dropped below programmable thresholds. LMT and ADC overload detectors (also referred to as …

122, UG-570 AD9361 Reference Manual | Page 122 of 128 Output Noise Spectrum Figure 89 shows the output spectrum of the ADP5040 switching regulator up to 1 MHz. This span is important, as the AD9361 is more sensitive to low frequency noise than it is to high frequency noise. Sw…

15, AD9361 Reference Manual UG-570 | Page 15 of 128 REFERENCE CLOCK SETUP AND OPERATION If the DCXO is not used, an external reference clock needs to be ac-coupled to XTALN (Pin M12). XTALP (Pin M11) is not connected (leave floating). The clock frequency must be between 5 MHz and 320…
