Return Loss is an alternate means to express VSWR. Directivity The power at the isolated port divided by the power at the coupled port Insertion Loss The input power divided by the sum of the power at the two output ports. At a given frequency (ωn), coupling is the input power divided by the power at the coupled port. Mean Coupling Mean coupling is the average value of the coupling values in the band. N is the number of frequencies in the band. Transmission Loss The input power divided by the power at the direct port Frequency sensitivity The decibel difference between the maximum in band coupling value and the minimum in band coupling value.

If this condition is not satisfied, insertion loss, Isolation and VSWR may not meet published specifications. All of the Xinger components are constructed from organic PTFE based composites which possess excellent electrical and mechanical stability. Xinger components are compliant to a variety of ROHS and Green standards and ready for Pb-free soldering processes. Pads are Gold plated with a Nickel barrier. An example of the PCB footprint used in the testing of these parts is shown below. In specific designs, the transmission line widths need to be adjusted to the unique dielectric coefficients and thicknesses as well as varying pick and place equipment tolerances. .41 .25 Plated thru holes to ground .33 .66 .04 4x Transmission lines Plated thru holes to ground Circuit Pattern Footprint Pad (s) Solder Resist Dimensions are in Millimeters Mounting Footprint 6 DC2337J5020AHF Rev H Packaging and Ordering Information Parts are available in reel and are packaged per EIA 481-D.
