10.14.1 Basic output configuration
10.14.2 DC interface to an Analog Quadrature Modulator (AQM)
10.14 Output configuration
The use of a differentially-coupled transformer output provides optimum distortion
performance (see
helps to match the impedance and provides electrical isolation.
The DAC1405D650 can operate up to 2 V
is recommended to connect the center tap of the transformer to a 62 Ω resistor connected
to the 3.3 V analog power supply, in order to adjust the DC common mode to
approximately 2.7 V (see
When the system operation requires to keep the DC component of the spectrum, the
DAC1405D650 can use a DC interface to connect to an AQM. In this case, the offset
compensation for LO cancellation can be made with the use of the digital offset control in
the DAC.
