New phase and amplitude stable flexible cable assemblies

Samtec, Inc. has announced the availability of full production quantity for its LL043 Series Nitrowave high-performance microwave cable assembly. Nitrowave is the company's new flexible, low-loss microwave coaxial cable product line that exhibits outstanding amplitude and phase stability in test and measurement and 5G datacom, defence, aerospace and computer/semiconductor applications. It is easily recognisable by its distinctive orange colour and is backed by Samtec Sudden Service, which includes part availability, quick delivery, and access to people and tools that help streamline a design process.

The optimised construction of the cable makes phase and amplitude stability with flexure possible. The inclusion of an interlayer allows consistent electrical performance throughout the cable's life span, while the low-density PTFE dielectric material ensures mechanical robustness. Flex life was tested to 400,000 cycles (with unrestrained flexing) and torque life to 1,000,000 cycles (+/-90°).

The series performance is optimised to 43.5GHz, with a maximum VSWR of 1.4:1. During product development, frequency capability was purposefully designed to go beyond conventional industry targets in support of advancing applications and spectrum allocation, allowing for 30% better insertion loss performance at next-generation frequencies. With consistent contact resistance between layers, state-of-the-art shielding techniques result in 100dB minimum shielding effectiveness against electromagnetic interference (per IEC 61000-4-21 specifications).

Connector end options include an SMA plug or SMA bulkhead jack (to 26.5GHz) or 2.92mm and 2.4mm plugs (to 43.5GHz). LL043 is available in standard assembly lengths of 305mm (12"), 610mm (24"), and 1000mm (39.37").
