Hi,
Why do most SDR transceiver architectures use a simple mixer at the receiver section & complex (I & Q) mixer at the transmitter section? What is the basis of choice for different types of mixer stages to be used in tx & rx sections of an SDR? Regds.

Both quadature modulator and demodulator are available. The real receive mixer is used when the IQ imbalance correction
for the receiver is not available.
