The high frequency low phase noise source circuit is an important and critical module for modern communication system. The design for high frequency signal sources is challenging, holds a promising future for application in 5G, IoT and improving the efficiency of modern communication systems. Reducing noise and power consumption become a major challenge in wireless, biomedical sensor, Radio identification device and deep space communication applications. As a vital factor affecting system cost and lifetime, energy consumption is an emerging and challenging research topic. This talk presents a practical design approach for low phase nose signal source targeting frequency from 10 MHz to 100 GHz operating frequency ranges. Examples are Crystal Oscillator, SAW Oscillator, Dielectric Resonator Oscillator, Planar Resonator Oscillator, and Opto-Electronic Oscillator.
