SUBMINIATURE COAXIAL CONNECTORS BMR-Spring GENERAL APPLICATIONS * * * * * * * * * Robust 50 DC - 8 GHz High power up to 350W at 2.7 GHz Board-to-board distance misalignment at least 0.078" (2 mm), custom misalignment of 3 mm+ * Tilt misalignment 6 max Broadcast RF components Wireless communications Military equipment Board-to-board connectors are becoming more and more popular for the use in RF equipment, which makes the system extra compact, reliable and cost effective compared to the traditional cable assembly solutions. Even in very high power and high frequency applications, connecting boards, modules or panels by rigid connectors are growing in popularity. The high-performance and robust BMR-Spring can handle a minimum boardto-board (or rack and panel) distance tolerance of 0.078" (2 mm) with custom misalignment of 3 mm or more. It also features a 6 tilt (radial travel). It has an operating frequency range of DC-8 GHz, a 1.1 max VSWR guaranteed up to 3 GHz, and it can handle up to 350 watts of power at 2.7 GHz. BMR-Spring also features a unique non-slotted spherical interface for improved electrical performance, high vibration and shock resistance, and an 80dB of shielding up to 3 GHz. A self-alignment mechanism makes the BMR-Spring particularly ruggedized for blind-mate applications. The spring-loaded adapters are symmetrical to avoid any assembly issues. A typical BMR-Spring board-to-board system is made of three parts: slide-on receptacle, symmetrical adapter, and snap-on receptacle. Custom configurations are available for board-to-board, module-to-module or rack and panel applications.
