Peak Power Handling  
High-Pot testing of these couplers during the qualification procedure resulted in a minimum breakdown voltage of  
1.7KV (minimum recorded value). This voltage level corresponds to a breakdown resistance capable of handling at  
least 12dB peaks over average power levels, for very short durations. The breakdown location consistently occurred  
across the air interface at the coupler contact pads (see illustration below). The breakdown levels at these points will  
be affected by any contamination in the gap area around these pads. These areas must be kept clean for optimum  
performance. It is recommended that the user test for voltage breakdown under the maximum operating conditions  
and over worst case modulation induced power peaking. This evaluation should also include extreme environmental  
conditions (such as high humidity).  
Orientation Marker  
A printed circular feature appears on the top surface of the coupler to designate Pin 1. This orientation marker is not  
intended to limit the use of the symmetry that these couplers exhibit but rather to facilitate consistent placement of  
these parts into the tape and reel package. This ensures that the components are always delivered with the same  
orientation. Refer to the table on page 2 of the data sheet for allowable pin configurations.  
Test Plan  
Xinger II couplers are manufactured in large panels and then separated. A sample population of parts is RF small  
signal tested at room temperature in the fixture described above. All parts are DC tested for shorts/opens. (See  
“Qualification Flow Chart” section for details on the accelerated life test procedures.)
