Description

Low Noise Amplifiers are devices suitable for detecting and amplifying low power radio signals without changing the electromagnetic properties of the signals. In order to achieve this, design requirements are such that these devices must be characterized by high performance parameters such ultra-low noise figures, high gain, high dynamic range, high sensitivity and stability in order to minimize signal quality loss during reception stage. Furthermore, device system temperature has to be controlled for high sensitivity requirements. Therefore, this poster presents a comprehensive review of different amplifier technologies and design techniques available for low noise amplifiers, specifically for radio astronomy applications. Furthermore, the poster gives an in-depth analysis of various design methodologies along with available device technologies, together with their advantages and disadvantages. In conclusion, the poster provides proper results simulations from existing related designs in order to solidify the choices to be made for the low noise amplifier design of the Two Antenna Radio Interferometry.
