The Bing Cable 2.92-K-SR020-110 is an SR020 miniature RF test probe pigtail designed for engineers who need repeatable RF performance in limited space. It is not simply a short piece of semi-rigid cable with a connector on one end. The assembly is built around a controlled SR020 cable platform, a precision 2.92 mm female interface, and an assembly-level verification process that takes place before the final center cut. This approach produces a stable cable-to-connector transition, strong unit-to-unit consistency, and less uncertainty during integration. The finished pigtail is 110 mm nominal and is available with a straight-cut end or a stripped lead prepared to an approved customer drawing. It is a practical solution for board-level RF signal injection, microwave module testing, prototype verification, laboratory fixtures, and compact fixed RF interconnections.

Conventional SMA test pigtails come with SMA female connectors, a maximum VSWR of 1.35:1 and a 6 GHz frequency rating. The Bing Cable 2.92‑K‑SR020‑110 is different. It features a precision 2.92 mm female interface that mates mechanically with SMA male and 3.5 mm male connectors, delivering extra interface margin while remaining compatible with existing test systems. Its key advantage lies in the validation process. Each pigtail is cut from a 220 mm two-port parent assembly, which is VNA-tested before center cutting. The parent assembly achieves VSWR below 1.10 on both ports and insertion loss under 2.5 dB at 10 GHz. This provides a tighter, more stable performance baseline compared to the common industry practice of testing only after final trimming. Finished cables can be supplied with straight-cut ends or custom stripped leads manufactured per customer drawings, with precisely sized dielectric and inner conductors for easy matching to specific launch and grounding structures.
