PIN CONFIGURATION  
electrical and mechanical stability having X and Y  
thermal coefficient of expansion (CTE) of 17 ppm/oC  
When a surface mount hybrid coupler 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. As long as the geometry  
of the unit fits onto the layout of the circuit trace on  
the PCB, and the conditions of the previous  
paragraph are followed, the coupler’s performance is  
ensured. 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.  
All of the standard surface mount 3dB hybrid couplers  
have pin orientations that are symmetrical. When a port  
is designated as the input, automatically the two output  
and isolated ports are defined. For example, if the input  
port for a device was selected to be Pin 1, Pin 2 is  
automatically the isolated port, Pin 4 is the 0 degree  
reference output port, and Pin 3 is the output port which  
“lags” behind the reference output port by 90 degrees.  
Similarly, if Pin 3 was to be selected as the input port,  
the adjacent port on the long side (Pin 4) is the isolated  
port, the adjacent port on the short side (Pin 2) is the 0  
degree output port, and the opposite port (Pin 1) is the -  
90 degree output port. Below is a table of all possible  
orientations.  
SUGGESTED FOOTPRINT  
To ensure proper electrical and thermal performance  
there must be a ground plane with 100%  
solder conection underneath the part

In order for Xinger surface mount couplers 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 plane under the part to ensure proper  
electrical performance. If either of these two conditions  
are not satisfied, insertion loss, coupling, VSWR and  
isolation may not meet published specifications.

Overall ground is improved if a dense population of  
plated through holes connect the top and bottom ground  
layers of the PCB. This minimizes ground inductance  
and improves ground continuity. All of the Xinger hybrid  
and directional couplers are constructed from ceramic  
filled PTFE composites, which possess excellent
