8 s parameter measurements the s-parameters are measured on a 0.016 inch thick ro4003 printed circuit test board, using g-s-g (ground signal ground) probes. coplanar waveguide is used to provide a smooth transition form the probes to the device under test. the presence of the ground plane on top of the test board results in excellent grounding at the device under test. a combination of solt (short C open C load C thru) and trl (thru C refect C line) calibration tech - niques are used to correct for the efects of the test board, resulting in accurate device s parameters. package and assembly note for detailed description of the device package, handling and assembly, please refer to application note 5378. ordering information part number devices per container container VMMK-3803-BLKG 100 antistatic bag vmmk-3803-tr1g 5000 7 reel package dimension outline reel orientation dimensions symbol min (mm) max (mm) e 0.500 0.585 d 1.004 1.085 a 0.225 0.275 not e: all dimensions ar e in mm a e d top view end view ? oy ? oy ? oy ? oy 8 mm 4 mm user feed direction notes: ?o? = device code ?y? = month code esd precautions note: these devices are esd sensitive. the following pre - cautions are strongly recommended. ensure that an esd approved carrier is used when die are transported from one destination to another. personal grounding is to be worn at all times when handling these devices. for more detail, refer to avago application note a004r: electro- static discharge damage and control. user feed direction carrier tape reel device orientation
