Peak Power Handling
High-Pot testing of these couplers during the qualification procedure resulted in a minimum breakdown voltage of 1.40
kV. 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 III 30dB 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.)
