Mounting Configuration:
In order for Xinger surface mount components to work optimally, the proper impedance transmission lines must be
used to connect to the RF ports. 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.
