TRANSMITTER SIGNAL CHAIN
Upconversion Mixer
The upconversion mixer translates the baseband signal to RF. It is an IQ modulator, which receives a quadrature baseband and LO signal. Due
to the image rejection property of IQ modulators, it produces an output only on one side of the LO, i.e., the image is rejected. The LO leakage
and quadrature errors of the mixer are calibrated at initialization, and continually tracked by the transmitter LOL and QEC, as discussed.
RF Attenuator
Following the mixer is a digitally controlled step attenuator with 64 linear gain steps. This results in a total gain range of 42 dB. Note that the
analog gain steps are not linear-in-dB. However, as pointed out in the previous section, the analog gain steps are interpolated by a digital
multiplier to achieve 0.05 dB gain steps. Note in the Direct FM/FSK mode, the total gain is 12 dB with 0.5 dB step size.

TRANSMIT DATA CHAIN API PROGRAMMING

There are a set of transmitter data chain APIs for interaction with the ADRV9001 device transmit datapath. Some of them are discussed in
the previous sections. The following table summarizes the list of available API functions with a brief description for each. For more up-to-date
information and detailed descriptions, refer to the API Doxygen document.
