Mounting
In order for Xinger crossovers to work optimally, there must be
50 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 50 lines need
to be adjusted to the unique dielectric coefficients and
thicknesses as well as varying pick and place equipment
tolerances.
