Microminiature Connector Products
I-PEX Connectors
’ new NOVASTACK® 35-HDN board-to-board connectors have a compact, fully shielded design with 10 or 30 positions on a tight 0.35mm pitch and a dual-shielded structure that effectively prevents EMI interference and supports high-integrity, high-speed data transmission in millimeter-wave (mmWave) applications including 5G modules and smartphones. The series is 53% smaller in total area than its predecessor, the NOVASTACK 35-HDP Series, measuring just 0.7mm high and 2.1mm in depth vs. 0.75mm high and 3.7mm in depth, and either 4.15mm (10p) or 7.90mm (30p) wide. Signal pins are rated for 0.3A per pin and power pins, which max out at 10 positions, are rated for 1.0A per pin. The series supports 10Gb/s USB 3.1 Gen 2, 20+Gb/s Thunderbolt™ 3, and 15Ghz mmWave operation and will eventually offer connector solutions with up to 60 positions. Microminiature Connector Products
Rosenberger
offers a wide range of RF coaxial connectors for PCB applications, including straight and right-angle solder- and surface-mount SMP, long-wipe SMP, P-SMP, Mini-SMP, FMC, Micro-RF, multiport, SMA, QMA, SMB, Mini-Coax, and MCX connectors, as well as RF coaxial connectors with custom footprints optimized for specific applications. Its Micro-RF connectors are amongst its smallest solutions for cable-to-board connections. These connectors have very small dimensions, measuring just 1.8mm x 1.9mm x 1.5mm (L x W x H), and provide excellent transmission quality in small wireless applications up to 6GHz. They also have a micro RF test switch to support the RF performance verification of antennas and circuits. In addition, like all of Rosenberger’s surface-mount RF coaxial connectors, the Micro-RF connector series employs patented surface mount coaxial connector (SMCC) technology that makes the coax to planar transition internally, within the connector. This feature, combined with optimized footprints, significantly reduces PCB layout development times.
