Cables wrapped in ePTFE tape prepare phased-array radars for 5G
At European Microwave Week (EuMW) in London (02 to 07 April), Junkosha will launch a range of ePTFE tape wrapped cables designed for phased-array radars.
The ePTFE tape wrapped phase and amplitude stable MWX7 cables are claimed to incorporate the lowest phase and amplitude deviation and best linearity over temperature and flexure. Junkosha said the MWX7 series has been developed to tackle the next generation of mmWave large-scale phased array radars.
Dr Shahriar Shahramian PhD, group leader (director) – Sensing & Communication ASICs Research for Nokia Bell Labs explained: “Next generation wireless communication systems continue to push the frontier of higher carrier frequency and data rates. With 5G networks we have seen the introduction of mmWave large-scale phased array radars as well as MIMO systems that require some of the most stringent phase/amplitude stability to date. Both characterisation and deployment of these systems rely on RF interconnects for synchronisation and to minimise drift over time.”
The MWX7 series of ePTFE tape wrapped cables deliver phase and amplitude stability vs temperature fluctuations. They also offer reduced phase and amplitude drift due to mechanical fluctuations, said the company. In-house dielectric ePTFE tape wrapping technology ensures consistent performance in both inter and intra batch quality.
Masaru Omoto, product manager for Junkosha, added: “With this new series of cables, we are answering the critical requirements of phase and amplitude stability against temperature fluctuations which are vital for phased array radars used in the defence sector. Extreme temperatures need to be managed so that there is no lag in response times to threat detection, the implication of which is massive”. He added that the ePTFE tape wrapped MWX7 series cable helps a radar system to have instantaneous responses in critical situations.
Junkosha specialises in fluoropolymer application technologies across many sectors including microwave interconnect and medical devices. It has three operations in Japan, including its headquarters; there are also sites in the US, UK and China.
The company provides wire and cable products, including microwave interconnects, robot cables, high data rate cables, camera link cable assemblies, fine coaxial cables and assemblies, cables for clean environments, and general wires and cables. It also provides tube and fitting products, including generic resin tubes, fluoropolymer tubes, high-barrier tubes, flexible multi-layered tubes, industrial hoses, degassing modules, heat-shrinkable tubes, and the market leading peelable heat shrink tubes.
