SIPU Successfully Delivers a Customized 18 GHz High-Temperature RF Cable Assembly

Recently, SIPU successfully completed the development and production of a customized high-temperature RF cable assembly designed for demanding high-frequency and high-reliability applications.

The assembly features a right-angle SMP connector and a reverse-polarity right-angle SSMA-K connector. It operates at frequencies up to 18 GHz and meets a voltage standing wave ratio requirement of VSWR ≤ 1.4. To ensure stable performance across multiple channels, the assembly also achieves phase consistency within ±5° and amplitude consistency within ±0.2 dB.

During production, GHL268 high-temperature solder wire was used to improve solder-joint reliability under elevated temperatures. X-ray inspection was performed on both the inner and outer conductor solder joints to verify soldering quality and detect any excess solder, foreign material, or internal defects.

The completed cable assemblies were also required to pass high- and low-temperature testing as well as temperature shock testing. These tests help ensure reliable electrical and mechanical performance under rapid temperature changes and harsh operating conditions.

This successful project demonstrates SIPU’s capabilities in customized RF interconnect design, precision manufacturing, high-frequency performance control, and comprehensive quality inspection.

SIPU remains committed to providing reliable RF connectors, cable assemblies, and customized interconnect solutions for aerospace, defense, test and measurement, communications, and other demanding applications.
