Directional couplers are used in a wide variety of applications to sense RF power, and they may appear at multiple points in a signal chain. In this article, Analog Devices explores the ADL5920, a new device that combines a broadband directional bridge-based coupler with two rms responding detectors in a 5 mm × 5 mm surface-mount package. This device offers significant advantages over conventional discrete directional couplers that struggle with the trade-off between size and bandwidth, particularly at frequencies below 1 GHz.
The next generation of MILCOM platforms will need to leverage more modern communication technologies that have been developed to enable commercial platforms such as cell phones and Wi-Fi.
This article compares the benefits and challenges of three common receiver architectures: a heterodyne receiver, a direct sampling receiver.
This article reviews the strengths and weaknesses of two electronic beamforming techniques: phase shifters (PSs) and true time delays (TTDs).
