The Receiver Noise Equation: A Method for System Level Design of an RF Receiver

Introduction to a new equation used to simplify the system level design of an RF receiver
Noise is a limiting factor for sensitive reception. In recent communication receivers, noise, along with many external factors, including intermodulation, reciprocal mixing and spurious response, may disturb the sensitive reception of the desired signal. Thus, much consideration for the noise and other factors that disturb the signal reception and...

The Development of Wide Angle Base Station Antennas from Arrays

Use of flat panel array base station antennas to produce wide angle beamwidths up to 120°
Phased array antennas are traditionally used to produce narrow beams from large apertures. In this mode of operation, every radiating element in the array is broadly co-phased. The radiation pattern of the antenna is then the product of both the individual radiating element characteristic pattern and the array factor....
