Notes on RF Testing and Circuit Layout
The XC0900A-20 Surface Mount Couplers require the use of a test fixture for verification of RF performance. This test
fixture is designed to evaluate the coupler in the same environment that is recommended for installation. Enclosed
inside the test fixture, is a circuit board that is fabricated using the recommended footprint. The part being tested is
placed into the test fixture and pressure is applied to the top of the device using a pneumatic piston. A four port Vector
Network Analyzer is connected to the fixture and is used to measure the S-parameters of the part. Worst case values
for each parameter are found and compared to the specification. These worst case values are reported to the test
equipment operator along with a Pass or Fail flag. See the illustrations below.
