Fairview Microwave, a supplier of on-demand microwave and RF components, has introduced a complete line of mini-DIN 4.1/9.5 adapters intended for use in applications requiring low passive intermodulation (low PIM) performance such as cell sites or indoor/outdoor distributed antenna systems (DAS).
Mini-DIN adapters used in RF applications are similar in design to 7/16 DIN connectors, but have a more compact body and offer more precise electrical performance. Fairview Microwave’s new 4.1/9.5 mini-DIN adapters offer excellent VSWR performance of 1.25:1 up to 6 GHz. Third-order PIM is guaranteed to be less than -160 dBc using 2 tones at 20 Watts. These low PIM mini-DIN adapters are available in male and female combinations of between-series interfaces for each adapter type including 4.1/9.5 mini-DIN to 7/16 DIN and 4.1/9.5 mini-DIN to Type-N. Two non-low PIM versions are also available.
New 4.1/9.5 adapters from Fairview Microwave are constructed with tri-alloy plated brass bodies and silver plated Beryllium Copper (BeCu) center contacts, allowing low IMD and low attenuation. Additional applications of Fairview’s new lines of 4.1/9.5 adapters include portable sweep testing, telecom installations, wireless infrastructure, OEM in-rack RF routing, in-building systems, and land mobile radio communications.
“This new line of low PIM mini-DIN adapters is ideal for wireless applications requiring low return loss, low IMD, and repeatable electrical performance”, says Greg Arnold, Technical Sales Manager at Fairview Microwave. “The high quality construction and tri-alloy plating help reduce nonlinearities that can cause distortion in critical communications equipment.”
