A local oscillator (LO) is an electronic oscillator that generates a very narrow bandwidth signal, or tone, with high purity and stability for use in frequency conversion circuits and timing. As the performance of frequency conversion circuits and timing systems are often dependent on the LO performance, the quality of the oscillator and LO electronic ..

Given the stringent timing requirements of 5G network and wireless applications, RF oscillator performance is of increasingly critical importance. Noise and phase noise are among the most significant of these requirements, as these parameters have the greatest impact on communication signal quality and receiver capability. Though noise and phase noise have always been RF oscillator ..

Though 5G comes with many promises of a ubiquitous high-speed experience with dramatically improved performance over 4G systems, there are several necessary upgrades to underlying technology and infrastructure that are necessary to achieve those desired ends. One such area is with timing and synchronization. In order to realize the desired 5G network responsiveness for high ..

In most RF systems, the production, transmission, and reception of a radio frequency signal is accomplished by way of a transmitter which amplifies and modulates the signal and a receiver system which feeds the signal into the mixer circuits to enable frequency conversion and demodulation. An oscillator is a circuit that generates a repetitive waveform, ..
