Phase Locked Dieletric Resonator Oscillators (PLDRO) is a type of oscillator that is used in millimeter-wave communication systems, where phase noise performance is of utmost importance. As wireless communication systems are advancing, the system manufacturers and service providers are all trying to transmit more data within the limited frequency resources available. To do so, they are using more advanced modulation techniques such as 16PSK or 128QAM. Generally, the phase noise of the data modulation index and local oscillator are very closely related. Phase noise of the local oscillator must decrease as the modulation index increases.
