Mounting
In order for Xinger crossovers to work optimally, there
must be 50Ω transmission lines leading to and from all of
the RF ports. Also, there must be a very good ground to
the corners of the crossover to insure proper electrical
performance. If either of these two conditions are not
satisfied, insertion loss, VSWR and isolation parameters
may not meet published specifications.
When a surface mount crossover is mounted to a printed
circuit board, the primary concerns are; insuring the RF
pads of the device are in contact with the circuit trace of
the PCB and insuring the ground plane of neither the
component nor the PCB is in contact with the RF signal.
Since the component is not symmetrical, the crossovers
are specifically oriented in the tape and reel. An example
of how the PCB footprint could look is shown below. In
specific designs, the 50Ω lines need to be adjusted to the
unique dielectric coefficients and thicknesses as well as
varying pick and place equipment tolerances.
Mounting Footprint
To ensure proper electrical and thermal performance
there must be a ground plane with 100%
solder connection underneath the part
