L Band Receiver Circuit Design and PCB Layout Review

This consulting activity consisted of reviewing detailed design schematics for a wideband L band receiver already designed by the client, and ensuring frequency plans, gain distribution, phase noise and thermal noise figure considerations were properly accounted for.  As well, detailed circuit implementation and passive and active component choices were reviewed.  Recommendations were made to improve components choices, power supplies decoupling and where to add test points to aid the development and manufacturing processes.

Circuit board layout recommendations were generated describing how to partition the circuits, which circuits should be shielded, what kind of shields should be used and where to place bypass and power supply decoupling components.  As well, recommendations were given for a RF friendly layer stack-up, power supply routing methods and where to put ground planes.
