Micro-miniature coaxial connectors suit a wide range of wireless applications

A new series of micro-miniature coaxial connectors developed by Radiall is now available at TTI. The MML Series is designed to address the market demand for smaller microminiature interconnects for applications such as WiFi access points, GPS and other mobile terminals. The Series includes plugs, receptacles, jacks, adapters, pigtails and cable assemblies. Offering an operating frequency range of DC to 6GHz and a typical VSWR of 1.35, the connectors feature space-saving plugs with mated heights of 2.5mm, 2mm and 1.5mm respectively. There are two types of vertical PCB receptacles: MML H2.5 and MML H2.0 with a PCB pattern of 3.08mm x 3mm; and MML H1.5 with a PCB pattern of 2mm x 2mm. Physical characteristics include bronze gold-plated bodies and gold-plated brass centre contacts. Operating temperature range for MML Series connectors is -40C to +90C. In addition, Radiall offers a variety of MML Series cable assemblies with three RoHS compliant 50ohm high-performance cables - 1.3mm for MML H2.5, 1.13mm for MML H2.0 or 0.81mm for MML H1.5. Other applications for MML Series micro-miniature coaxial connectors include micro base station enclosures, computers, measuring equipment and energy-management systems.
