Customizations

SV Microwave offers a flexible approach to customizing our COTS products to meet unique customer needs. Our applications and design engineering teams routinely make minor adjustments to standard parts-such as lengthening flanges, adjusting retention features, or altering PCB connector lengths—to support specific design requirements. Below are some examples.

Part number 1211-66452, although a standard product, originated from a customization of the base of part number 1211-66137. In this case, the modification involved extending the PCB length and adjusting the flange to enhance performance.

Center contact retention can be achieved in a connector in several ways, depending on the dielectric material. PTFE, for example, uses a barb captivation method to hold the center contact in place within the body of a PCB connector. While this captivation method stops the contact from moving back and forth, it still allows for radial movement.

Radial captivation is achieved with a glass seal or epoxy dielectric design. The contact is fused to the glass or epoxy dielectric, which provides excellent center contact retention in both the axial and center rotations.

PTFE / Barb Captivation PTFE, as a dielectric, features a barb that affixes the center contact in place, but still allows for rotation.	Glass or Epoxy Seal Captivation Glass or epoxy material as the dielectric prevents center contact rotation.

SV Microwave is able to take an existing COTS cable assembly and modify it in any number of ways including: changing the cable type to a larger or smaller cable diameter, increasing or shortening the length, or swapping out one of the cable connectors, for one of a different RF interface. Below are two COTS examples where a cable assembly has been modified for a shorter length, and different cable diameter.
