 Unfortunately, the measurement data exceed the isolation specifications in datasheet.
 ===== Summary =====
-The testing fixture meets my expectation for working within 0GHz to 6GHz. No comment for the SPDT RF switch.
+The testing fixture meets my expectation for working within 0GHz to 6GHz. For the isolation, I think the IC may conform to the isolation specifications, because de-embedded algorithm cannot work with crosstalk problem. Crosstalk between the traces RF1 and RF2 on the PCB can downgrade the isolation.
