Mean Coupling
Definition
The impedance match of the
coupler to a 50Ω system. Return
Loss is an alternate means to
express VSWR.
The power at the isolated port
divided by the power at the
coupled port
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 is the average
value of the coupling
values in the band. N is the
number of frequencies
in the band.
Phase Balance
The difference in phase angle
between the two output ports.
Frequency
sensitivity
The decibel difference between
the maximum in band coupling
value and the minimum in band
coupling value.

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.
