Over the past 55 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, 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.

Aeroflex / 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.

Aeroflex / Weinschel’s 35,000 square foot facility, located in Frederick, Maryland, is certified to ISO 9001-2000 standards.

Weinschel Engineering, Co., was the first to design and manufacture commercially available coaxial attenuators. From the company's very first DC-1 GHz tee attenuator, came the technology that enabled the design of the first DC-5 GHz, the first DC-10 GHz, and the first DC-18 GHz coaxial attenuators. These designs led to the development of the distributed resistor card attenuator element, which is the basis for most all attenuators manufactured today from DC-60 GHz. Until the original patents expired a few years ago, most major attenuator manufacturers in the U.S. were licensed under one or more Weinschel Engineering, Co., patents.

Today, their product line includes a wide variety of standard and custom designed fixed, continuously variable, manual and motorized step, and programmable binary step attenuators covering the DC to 40 GHz frequency range, at power levels up to 1,000 watts. Aeroflex / Weinschel is also a major supplier of HI-Rel MIL-3933 and Space qualified attenuators.


The superior performance Aeroflex / Weinschel components enjoy is due to their connector design capabilities. Utilizing proprietary design techniques, they offer connectorized devices that are mechanically robust, stable over environmental extremes, and highly reliable. They offer a comprehensive line of between-series adapters, blind-mate connectors, and their patented PLANAR CROWN® Connector System.

The company's Planar Blind-mate Connector Series provides threadless connector mating which is useful when mating an array of connectors from one RF module to another in seconds with a "Forgiving" Mechanical Interface that can permit a 0.02 Mis-Alignment. These connectors offer dc to 40 GHz operation, a contact life of 1.0 m cycles and a repeatability of 0.05 dB typical per connection. Other features of this connector series include pressurized and unpressurized designs, SMA and SMB connector options, space saving, and rugged construction.

Aeroflex / Weinschel offers a comprehensive product line of coaxial Terminations, Power Dividers, and Power Splitters. Many of these standard products were designed for particularly demanding boradband requirements, SWR, and high power system applications. As with the development of all Weinschel Corporation products, high performance at competitive prices is of paramount importance.

Although the Aeroflex / Weinschel product line contains a wide variety of standard components, a substantial portion of their revenues is generated through the sales of custom components developed with internal funds. A large majority of these customized products are the result of adapting a standard or generic product to specific customer needs. This process provides their customers with reliable, high quality products at competitive prices to meet demanding technical and schedule requirements.


Aeroflex / Weinschel offers a wide selection of Programmable Attenuators that operate over the dc-26.5 GHz frequency range. Their programmable attenuators offer many features such as long switching life, high reliability, choice of standard attenuation and frequency ranges, long-term stability, quality connectors, and custom designs. Applications for these programmable attenuators are and have been primarily in areas demanding broadband accuracy with low SWR and accurate repeatability over large attenuation ranges. The Aeroflex / Weinschel Programmable Attenuators are widely used in many types of wireless, ATE and OEM systems operating throughout the world.

Aeroflex / Weinschel has recently added a number of new models to its product offering such as wireless models operating from dc-1.2 GHz in a variety of attenuation ranges and step sizes; 75 ohm models (dc-1 GHz, 0-63 GHz); a SmartStep® Series (3200T, 150T); 3 GHz models (see 3200 & 3200T Series; and a new series of GaAs & Pin switched that operate to 2.5 GHz with many step sizes.
