For over sixty years the name Weinschel has become synonymous with leadership in RF and microwave technologies and superior quality components and subsystems for wireless, defense, test and measurement, and broadband markets throughout the world. Among its many technological achievements, Weinschel was the first to design and manufacture commercially available coaxial attenuators. Today, built upon a strong heritage, Weinschel (formerly Aeroflex / Weinschel) continues to provide a vast array of standard products together with custom-engineered solutions to satisfy demanding market needs for precision and high reliability coaxial components.
Weinschel's product offering includes fixed attenuators for test, metrology and space applications; continuously variable, manual step, solid-state digital step and programmable step attenuators; high power terminations; resistive splitters and dividers; manual phase shifters; Planar Blind-Mate ®, Planar Crown ® connectors. In addition to coaxial components covering DC-40 GHz, Weinschel offers a complete range of standard and custom-designed SmartStep ® multi-path switching, combining, and attenuation subsystems for cable infrastructure and mobile wireless test applications, including RF simulation, multi-path and fading, high-power hot-switching attenuation, RF signal conditioning, RF and IF signal routing, and production testing.
Weinschel's 35,000 square foot facility, located in Frederick, Maryland, is certified to ISO 9001-2008 standards.
