Quality Wireless & Microwave Components & Subsystems

Weinschel develops, manufactures, markets, and sells high quality microwave and RF components and subsystems for wireless mobile and broadband infrastucture and test applications. Weinschel's mission is to provide superior design capabilities, products of consistent high quality, innovative solutions, and a high level of service to help its customers compete in today's demanding world markets.

The company was founded in the 1940's and offered the world's first commercially available coaxial attenuators. In 1952, the company founders formed Weinschel Engineering Co. and continued to pursue the advancement of microwave technologies. In 1994, Weinschel Corporation's Quality Management system is approved to: ISO 9001, EN 29001, BS5750: Part 1: and ANSI/ASQC Q9001-1994.

Weinschel products are used in standards laboratories, OEM, and quality control departments of most electronic and aerospace companies as well as government agencies and private research firms throughout the world. Applications include satellite and ground communications systems, electronic warfare and countermeasures, missile guidance, radar, OEM, signal analysis, telecommunications, air traffic control, and precision microwave related instruments and system use. Our product line includes:

•Fixed Attenuators & Terminations
•Variable & Manual Step Attenuators
•Programmable Step Attenuators
(Relay & Solid-State)

Crown® Connector Systems
•SmartStep® Subsystems (Switch
Matrices, Cable ModemTesting,
Controllers, Attenuation Modules &
Multi-Channel Subsystems)
•Phase Shifters & DC Blocks
•Customized Products

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 commerical 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, our product line includes a wide variety of standard and custom designed fixed, continuously variable, manual step, and programmable binary step attenuators and terminations covering the DC to 40 GHz frequency range, at power levels up to 1,000 watts.

Weinschel is also a major supplier of HI-Rel MIL-3933 and Space qualified attenuators.

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

Our 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.


Weinschel offers a comprehensive product line of Power Dividers, and Power Splitters. Many of these standard products were designed for particularly demanding broadband 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 Weinschel's product line contains a wide variety of standard components, a large number of our sales are custom products that are mainly a result of adapting a standard or generic product to specific customer needs. This process provides our customers with reliable, high quality products at competitive prices to meet demanding technical and schedule requirements.

Weinschel's Smartstep® design approach provides the customer with a flexible, low cost solution for the operation and packaging of programmable step attenuators and other components such as power combiners/dividers/ splitters, amplifiers, switches, filters, etc.

Options can include standard controller interfaces (IEEE-488.1, RS-232, RS-422 ethernet and others); multiple attenuation/switching schemes; individual to complex matrix/channel configurations; specialized testing and calibration; and customized packaging. These subsystems are ideal for use in specific test, simulation and emulation of cellular, PCS, wireless, mobile, cable and telecommunication applications.
