Phase Noise Profiles Aid System Testing
Noise is present in every system. Phase noise, in particular, is commonly found in oscillators and phaselocked loops can degrade the performance of a system. Phase noise in the oscillator of a wireless communication system degrades the receiver's sensitivity in reciprocal mixing conditions.
Three Methods of Noise Figure Measurement
In wireless communication systems, the "Noise Figure (NF)," or the related "Noise Factor (F)," defines the noise performance and contributes to the receiver sensitivity.
Specifications and Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers
Residual phase noise from local oscillators (LO) can be degraded by additive noise of on-chip local
oscillator drivers/buffers in integrated circuit mixers. Reciprocal mixing of strong RF signals with the LO noise degrades the receiver sensitivity.
Basic Equipment Design Tutorial
For any given piece of RF/Microwave hardware there
has to be a specification, which defines the electrical,
mechanical and environmental performance of the
equipment
