X2BS - Anaren

Model X2BS
Rev. B
SMT Crossover
Description
The X2BS is a low profile crossover to intersect an RF and RF circuit trace
in an easy to use surface mount package designed for frequencies up to 6
GHz. The X2BS is ideal for any application where an RF circuit must
intersect with another RF circuit without resorting to a multilayer PCB. Parts
have been run through rigorous qualification testing and units are 100%
tested. They are manufactured using materials with x and y thermal
expansion coefficients compatible with common substrates such as FR4, G10 and polyamide.

Mounting Footprint
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.
