In this paper, the authors present the design and implementation of a microwave oscillator circuit with ultra-fast amplitude control for an inspection system appropriate for real-time measurements of continously streaming materials. The material passing through the resonator of the oscillator changes the resonance frequency and the quality factor of the resonator. This influences the oscillation frequency...
For phased array receivers, mutual coupling leads to beam-dependent active impedances which must be taken into account when matching the array ports to front end amplifiers for optimal noise performance. We study the noise penalty for several noise matching conditions and develop a matching condition that minimizes the average beam equivalent receiver noise temperature over multiple beams. For non-beamforming...
In this paper, we study the noise penalty caused by mutual coupling for a phased array beamformer using the beam equivalent receiver noise temperature and noise matching efficiency developed in previous paper.. We also define an available receiver noise temperature correlation matrix, which provides an intrinsic or beam independent way to characterize the goodness of an amplifier noise matching condition...
