Mounting Footprint

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.
