Dynamic sub-sampling radio frequency mixer systems and methods

A direct conversion receiver, comprising:

• a wired connection to a conducted, distributed Radio Frequency (RF) system;
• in-phase mixer circuitry receiving a filtered input from an RF device and providing an output of a baseband signal of the RF input sampled at a sub-sampling rate;
• quadrature mixer circuitry receiving a filtered input from the RF device and providing an output of a baseband signal of the RF input sampled at a sub-sampling rate;
• baseband parametric control circuitry receiving the baseband signal and measuring at least one parametric value of the baseband signal;
• and
• sampling period control circuitry receiving the at least one parametric value and determining a mode of operation and adjusting the sub-sampling rate based thereon, wherein the sub-sampling rate is adjusted to minimize power drain while ensuring performance of the at least one parametric value is satisfying a predetermined level.
