Custom MMIC recently developed a Tech Brief to help you simplify your biasing design approach, reduce your bill of materials, and reduce extraneous noise sources with Low Noise Amplifier MMICs (LNAs) that utilize only a positive bias.
In modern RF and microwave communications and radar systems, the range of parameters an engineer must consider while optimizing a design is staggering. Not only must your high frequency electrical requirements be achieved, but physical and thermal constraints must increasingly be given attention. In this Tech Brief, you’ll learn how to reduce your signal chain's bill of materials, simplify your bias circuitry, and reduce the number of extraneous noise sources with Low Noise Amplifier MMICs (LNAs) that utilize a positive bias. The improvement in your future design approach from positive bias MMICs will not only be in your bias procedure, the effects will be felt across the board.
