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.
