Junkosha is showcasing its 7 Series Phase Stability cable assemblies at the AMTA 2026 Annual Meeting and Symposium in Austin, Texas. The assemblies are designed to maintain low phase and amplitude deviation and linearity over temperature.

Why it matters

Millimeter-wave radar and large-scale MIMO phased arrays operating at high frequencies depend on cabling that keeps phase and amplitude consistent. Temperature variation can otherwise degrade signal stability in these systems.

The 7 Series Assemblies operate at frequencies up to 67 GHz and come in cable sizes of 0.120, 0.086, 0.070 and 0.047 inches. Junkosha reports the cables use its proprietary EPTFE dielectric technology, though independent validation of the stability claims is not provided.

The players

Junkosha

Junkosha is a Japanese manufacturer of specialty fluoropolymer materials and high-frequency cable assemblies used in RF and microwave systems.

The details

The 7 Series Assemblies use Junkosha's proprietary EPTFE dielectric to deliver phase and amplitude stability across temperature fluctuations. Junkosha is exhibiting at booth 406 during the AMTA 2026 event.

The Tech Race

Phase-stable cabling is becoming a key enabler as mmWave radar and phased-array systems move to higher frequencies. Junkosha's EPTFE-based 7 Series positions the company in this specialized segment of the RF interconnect market.

Engineers designing mmWave radar, phased arrays and MIMO systems can evaluate the 7 Series for applications where phase and amplitude stability across temperature matters. The product's availability in four cable sizes gives designers options for different system packaging constraints.

The takeaway

Stable phase and amplitude across temperature is a practical requirement for high-frequency radar and array systems, making cable performance a design consideration rather than an afterthought. Engineers evaluating RF interconnects should compare temperature-stability specifications when selecting assemblies for mmWave and MIMO hardware.
