I want to design a AD8318 PCB which works at 4 GHz frequency range with bitrate (or datarate) of 5 Mbps. Can someone guide me as to how to design a PCB for the same? I am not sure of what needs to be done for the load matching.
We provide gerber files for the AD8318 evaluation board on the product webpage. (http://www.analog.com/en/specialty-amplifiers/log-ampsdetectors/ad8318/products/EVAL-AD8318/eb.html). This along with the 'Evaluation board' section on the datassheet should serve as a good reference point. Page 13 on the datasheet provides information about the output interface of the device.
