The ADF5904 is a highly integrated, 4-channel, 24 GHz receiver downconverter MMIC with the industry’s best combination of low noise performance, high linearity, and low power consumption.
The ADF5904 integrated, multichannel receiver downconverter achieves a 10 dB noise figure that is 3 dB better than competing devices. While using 50% less power, it is assembled in a small, cost-effective 5 mm × 5 mm LFCSP plastic package.
Each of the device’s four on-chip receive channels use a simple, single-ended connection to four individual antennas, which simplifies RF transmission line design and PCB layout, and reduces board size.
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).
