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.)
