RF

Selecting a RF connector

The factory product catalog lists 2 RF model records. Across those records, pitch is not stated in the sourced records; mated height is not stated in the sourced records; and contact count is not stated in the sourced records. These are ranges observed in the listed variants, not a substitute for a controlled drawing of the exact order code.

RF interfaces must be selected as part of an entire signal path. The cable or board launch, enclosure opening and mating access all affect whether a particular connector can be integrated.

Begin by drawing the two surfaces that must be joined. Record the board outline, location of each connector, approach direction and space available for a mating operation. If a cable or harness is involved, include its exit path and bend allowance. This basic sketch exposes conflicts that a list of nominal electrical values cannot show. The connector should be evaluated as part of the complete assembly, rather than as an isolated component photograph.

Start with the mechanical interface and the sourced catalog description. Ask for the current drawing and relevant electrical test data before defining the layout or comparing an RF candidate with another family.

Next, fix the actual contact assignment. Record signal, ground and power positions, and note any contacts that need a separate current review. Compare the pin count listed for the exact catalog record with the circuit plan. A higher count can increase routing and board-space demands, while a lower count may leave no room for future revisions. A selection table is useful for narrowing candidates, but it does not replace a pin assignment or a released drawing.

Compare sourced catalog records

The records below are generated from the current factory product data. A value marked Pending confirmation has not been accepted as a verified part-level specification. Select the linked model to see its drawings, mating notes and the source attached to each available value. If a project depends on a tolerance, current rating or environmental result, request the controlled file and identify the specific test condition.

The comparison table links to all 2 model records across 2 base series names. Where two models share a base series, their suffixes may still identify a different contact count, gender, height or geometry. The exact order code should travel with every drawing request, quotation draft and engineering note.

Mechanical and electrical review

Check the recommended PCB land pattern against the board stack and placement tolerances. Keep assembly tooling, inspection access and any enclosure interference in view. Review connector retention and the intended mating sequence before freezing the mechanical design. For an electrical review, use the model-level current and voltage values only where the catalog or controlled specification actually states them. Assess signal performance in the finished board or cable channel rather than treating a connector family name as proof of system performance.

Frequency capability, insertion loss and impedance are not implied by the family name. Leave any unverified performance target open until the exact model and test evidence have been reviewed.

Document the remaining questions before requesting samples. A useful engineering inquiry includes the candidate model, board layout, target mated height, contact assignment, expected quantity, project stage and the tests required by the destination product. Ask for the latest datasheet revision and a matching two-dimensional or three-dimensional drawing when available. If any value on this page differs from a newly released controlled document, the current document should govern the design review.
