The mixer includes an LO driver and a low noise output amplifier and provides both user-programmable power consumption and third order intercept point. The AD831 provides a +24 dBm third order intercept point for –10 dBm LO power, thus improving system performance and

The coherence time and Doppler spread are inversely related: 1 CoherenceTime Doppler Spread ≈ Thus, if the transmitter, receiver, or the intermediate objects move very fast, the Doppler spread is large
