Noise Considerations in Broadband Microwave Power Amplifiers

RF/microwave power amplifiers used in test and measurement applications are typically characterized by their broadband frequency range, high gain with relatively flat frequency response, low noise and wide linear range. RF/Microwave amplifiers are characterized by their noise figure. Giga-tronics microwave power amplifiers have relatively low noise figure, ideal for applications where a combination of broad frequency range, high power and low noise are required. This application note discusses noise considerations in broadband microwave amplifiers.
