Managing Phase Noise in Microwave Chains

This work encompases a set of phase noise and some other rules for microwave oscillator design in microwave receiving and transmitting chains intended for SDR radio systems. Engineering shown in this work, comes from error vector magnitude achievable in a system. A 10 dB difference between demanded EVM and CINR is a reserve needed for compensating of various errors, wich are inevitable caused by the elements in the frequency conversion chain. Using this design process, post-layout simulations show a phase noise of -110 dBc/Hz at the offset of 100 kHz.
