Rigid Waveguide Components

Mega Industries provides high power, low frequency waveguide and waveguide components in sizes ranging from WR090 through WR2300. Larger sizes are offered through WR5900 upon special request.

Waveguide are manufactured from 6061-T6 aluminum alloy, however, sizes WR090 through WR650 are available in either copper or aluminum alloys. Waveguide flanges and gaskets are provided in accordance with EIA and Military Specifications.

Mega Industries rigid waveguides are manufactured to precise tolerances calculated to provide optimum VSWR and maximum power handling capabilities.

In addition to straight waveguide, Mega offers a complete line of components to complete or refurbish your systems. These include miter bends, sweep bends, quadrature hybrids, magic tees, folded tees, series and shunt tees, transformers, transition, gas barriers, couplers, terminations, attenuators, phase shifters and tuners.

Our technical staff are on hand to assist you in developing and manufacturing specialized equipment at your request.

Flanges

Flush waveguide flanges in 6061-T6 aluminum plate are available for prototype fabrication or field installation.

Folded Magic Tee

For monopulse applications or when the use of standard magic tees presents a mechanical interfacing problem, folded tee configurations are available to our dimensions or custom designed to your specific system requirements.

Gain Horn

Mega Industries Standard Gain Horns have a wide range of applications such as transmitting, receiving or sampling. The high precision manufacturing of the Mega Gain Horns assure you of accurate, repeatable gain reference. Horns are built and manufactured per the NRL standards, Report #4333.

Gas Barrier

For optimum performance, we recommend that your microwave feed system be maintained under a slight positive pressure to prevent the entrance of moisture or other contaminants.

Harmonic Filters

Mega offers a complete range of waveguide reflective and absorptive harmonic filters to meet the stringent system requirements necessary in today's marketplace.

High Power Loads

Mega Industries manufactures a wide range of waveguide terminations ranging from instrument level, low power test terminations to very high power system loads. The low power test terminations may be supplied in either a fixed or an adjustable configuration to best meet the needs of the customer.

Impedance Matchers

For extremely high power applications, impedance matchers of the short slot hybrid design are utilized.

Magic Tees

A line of Magic tees manufactured to exacting electrical and mechanical specifications are available for every system layout. Our manufacturing processes provide maximum symmetry in fabrication and resulting in the following electrical performance over a 10% bandwidth.

Miters

Mega Industries high quality 90° waveguide miter bends are of minimum physical size and provide superior electrical performance over a restricted bandwidth (typically VSWR 1.03:1 over a 5% bandwidth).

Phase Shifters

For extremely high power applications, waveguide phase shifters of the short slot hybrid design are utilized. Non-contacting, double bucket shorting assemblies, mounted on Teflon runners, are utilized for long term reliability.

Rotary Joints

Mega Industries' waveguide rotary joints are designed specifically to customer requirements. These joints represent "State-of-the-Art" designs with extremely low VSWR and insertion loss.

Short Slot Hybrids

Quadrature, or 90 degree, equal power division hybrids are available as a basic subsystem building block. These units meet, as a minimum, the following electrical specifications over a 10% waveguide bandwidth:

Straight Sections

Mega Industries provides waveguide in sizes WR90 through WR2300. Full and reduced height configurations are available to meet your requirements. Custom sizes through WR6200 are also available on special request.

Sweeps

Mega Industries utilizes the most advanced fabricating methods for the forming of precision waveguide sweep bends. Strict adherence to EIA dimensional tolerances insures a minimum reflection coefficient over the waveguide band. Typical VSWR is 1.05:1

Switches

Mega Industries offers a comprehensive line of waveguide switch configurations, both manual and motorized, to meet the requirements of your microwave transmission system.

Tees

A complete line of series and shunt tees manufactured to exacting electrical and mechanical specifications are available for every system layout.

Our manufacturing processes provide maximum symmetry in fabrication and resulting in the following electrical performance over a 10% bandwidth.

Test Terminations & Short Circuits

Mega Industries manufactures a wide range of waveguide terminations ranging from instrument level, low power test terminations to very high power system loads. The low power test terminations may be supplied in either a fixed or an adjustable configuration to best meet the needs of the customer.

Transformers

Mega Industries offers a complete line of waveguide reducing transformers to the next standard size waveguide.

Transitions to Coaxial

Mega Industries manufactures a complete line of waveguide to coaxial transitions. For laboratory testing or other low power applications, we recommend “Probe type” transitions to type “N” coaxial line; while our low VSWR “cross-bar” design provides optimum electrical performance for high power applications.

Tuners

Mega Industries complete line E-H Tuners offer a form of in line waveguide structures to be used for impedance matching. These units, which will match out up to a 4:1 VSWR at any phase angle throughout the band of operation, utilize Mega Industries non contacting, single or double bucket short circuit designs for high power operation. Low power versions are also available utilizing contacting short circuit designs.

Twists

When mechanical system packaging necessitates a change in the plane of polarization, Mega Industries waveguide step twists provide an accurate electrical and mechanical interface. Our compact three-step waveguide twist exhibits a VSWR less than 1.05:1 over a 10% bandwidth. Lower VSWR's or increased bandwidth can be realized by utilizing a five-step twist.
