RF tiptoes into the embedded world
DoD has challenged microwave designers with creating subsystems with performance at or in some cases beyond the state of the art - and were just happy to get something that works, even at high cost.
- Thomas Edison
This quote from the famed inventor succinctly stated one of the two reasons why microwave subsystems - integrated microwave assemblies (IMAs) - employed in defense systems have never conformed to open standards such as OpenVPX. The second reason is that the U.S. Department of Defense (DoD) never required such conformation, until recently. Designers of board-level embedded products that adhere to specific, fixed form factors and electrical specifications might consider such a scenario chaotic, even ridiculous. To provide some perspective about why it's taken 70 years for the defense industry to tiptoe into open standards, we need to look at both the technology and the DoD.
