Automatic Fixture Removal (AFR) is a simple and an accurate way to de-embed a measurement fixture. These fixtures are typically used when measuring Surface Mount Device (SMD) type components to provide an interface from the Vector Network Analyzer (VNA) test port cables to the Device Under Test (DUT). The main challenge when characterizing such components is to completely isolate the actual DUT characteristics from the fixture; which becomes even more challenging at higher frequencies.
