INTRODUCTION MEG was established in 1993, as a small department in local Israeli company. MEG’s team, consisting of top Israeli experts in the fields of RF, mechanical design and manufacturing technologies, gained over the years an enormous experience in the development, design, production and testing of microwave passive components, antennas and integrated sub—systems.

MEG Ltd. is an independent company focusing on one and only purpose:

MAKE THE BEST PASSIVE MICROWAVE PRODUCTS.

In MEG, we give each of our customers the freedom to choose all the parameters for the product he needs. That’s why MEG specializes on customized products and sub-systems as well as standard ones.

After you’ll find the product you need, please contact us per the details below, and we will propose you with the best configuration available. Please fill free to consult our engineering staff to find the best solution to the problem you have, whether it’s the choosing of right parameters for your component, improving an existing sub system or building a new one.

Quantities: MEG is able to produce any quantity needed – from single units demanded for customer’s prototype to thousands of units.

Prices: Although usually developing and producing customized single units is a bit more expensive that ordering a large quantity, in MEG we work hard to reduce to minimum NRE and manufacturing costs. We are able to do it because we use the most experienced engineers, the best software, and the most advanced manufacturing technologies.

Custom Bended Waveguide

In MEG Ltd., we are all dedicated to fit customer’s special needs. With over 30 years of experience, we can solve your most complex waveguide lines problems, and over the years we’ve completed dozens of projects with custom waveguide run installations. Maintaining low insertion loss, similar to straight section, and relatively low VSWR, you can be sure that your custom design will not affect the electrical parameters.

Please consult MEG every time you need a special, custom designed waveguide.

• VSWR (max, for typical lines): 1.1 (Rectangular), 1.15 (Double Ridge). • Waveguide size: Rectangular / Double Ridge, For frequency specifications refer to table

1-3 • Material: Aluminum / Copper • Design – On request • Flanges: Refer to table 1-3 • Plating: Silver plated, gold plated, other (on request) • Finish: Passivized / Painted (On request)

Flexible Waveguide Sections

Flexible waveguide sections include Rectangular, Double Ridge and Elliptic Waveguides. These sections can be manufactured from Be-Cu or Brass, and fitted with flanges according to customers demand (to the list of standard flanges to various waveguides please refer to table xxx). General specifications:

o Frequency Limitations: From 0.5 MHz up to 40 GHz. o Waveguide Types: Flexible (one direction bending), Flexible Twist (2-D bending) o Rectangular Waveguides: WR-28 thru WR-650 o Double Ridge Waveguides: WRD180 thru WRD350 o Elliptic Waveguides: Waveguide sizes available per request

THE MOST COMMON problem with flexible waveguides is the fracture appearing in the connection between the flange and the waveguide. This failure is very common especially on long flexible sections, mainly in laboratories, when the waveguide is folded over and over again.

MEG HAS FOUND THE SOLUTION TO THIS PROBLEM. With specially designed flanges, the risk of such a failure is reduced to minimum – that’s why MEG’s flexible waveguides are working for years without the need of replacement.

If you need a NEW FLEXIBLE WAVEGUIDE, or if you wish to FIX BROKEN SECTION, do not hesitate to contact us.

Radial Power Dividers

MEG’s radial combiners and dividers combine or divide in a “single step”, maintaining losses to minimum. The design is air-dielectric and purely reactive, those avoiding heat sinking, associated losses, topology interferences, and other problems. These dividers are precisely manufactured, and their simple and rugged design is well-suited for harsh environments and field maintaining.

MEG’s combiners and dividers can be used on complicated amplifier systems, when there’s a chance for failure of one or more amplifier modules while operation continuity is critical.


Ø Ports: 4 to 90 (coax) Ø Frequency Range: 1 to 30 GHz Ø Power Handling: up to 50kW CW typical (higher power

Power Samplers MEG Series of Power Samplers consist of a capacitive probe coupled to the waveguide. Since these signal samplers have zero directivity they should be used only for power monitoring in well matched lines. The coupling between the waveguide and coaxial line can be adjusted to any value in the range of -30 dB to -60 dB. The frequency sensitivity of the coupling is + 0.5 dB over the whole waveguide band.

• Horn Antennas • Spiral Antennas • Dish Antennas

Other Antenna Types that we offer but do not mentioned explicitly in the catalog:

• Sectoral Horns • Septum Horns (i.e. Horn divided into sub-horns) • Aperture-limited Horns • Corrugated Horns – Corrugated Antennas can be manufactured on request, based on

the horn antennas described below. Corrugated horns have wider bandwidth and smaller sidelobes and cross-polarization; therefore they are a modification to given antenna. Please consult MEG engineering staff on this issue.

• Log Spiral Antennas • Helical Antennas • Slot Array Antennas • Bi-Conical Antennas

Broadband (Double Ridged) Horn Antennas

The MDRH Series Double Ridged Horns cover multi-octave frequency bands, providing linear vertical or horizontal polarization.

Applications for these linearly polarized constant gain horns include use as primary transmit / receive microwave antennas for EMI / RFI measurements and antenna test ranges for gain and pattern measurements. The precision fabricated internal ridged construction assures high repeatability between different production units.

A wide range of mounting solutions can be provided for various installation requirements (i.e. masts, tripods or antenna pedestals). For details please contact MEG engineering staff.

Other options of MDRH Horns include: Hermetically sealed Radome, Gain vs. Frequency Calibration Chart Radiation Pattern Records and Special Connectors.

Ø Frequency Range: 0.7 - 40.0 GHz, with over 30 GHz width bands available. Ø Polarization: Linear Ø Shape: Pyramidal or Conical, depends on bandwidth, gain and size required. Ø Material: Aluminum 6061-T6 (for F < 26 GHz), Brass ( for 26<F<40 Ghz), or Copper Ø Gain: 10 – 25 dBi upon request. Ø Size: Depends on Gain parameter.

Dual Polarization (Quad Ridged) Broadband Horn Antennas

The MDPH Series Dual Polarized Horns cover octave and multi-octave frequency bands, providing simultaneous vertical and horizontal polarization. By attaching a 90° Coaxial Hybrid these horns can provide RH or LH circular polarization as well. The MDPH Series Horns are designed for high gain parabolic reflector feeding, but they are well suited as primary radiator antennas for many applications. The precision fabricated internal Quad-ridged construction provides high isolation between the orthogonal input ports.

For various customer installation requirements (i.e. masts antenna pedestals, reflector struts) a wide range of mounting solutions can be provided. For details please contact our engineering staff.

Other Options of MDPH Horns include hermetically sealed Radome, Gain vs. Frequency Calibration Chart and Radiation Pattern Records.


Ø Frequency Range: 0.5 - 18.0 GHz in different bands (Per request) Ø Polarization: Vertical & Horizontal Ø Shape: Pyramidal or Conical, depends on bandwidth, gain and size required. Ø Isolation between Input Ports: 25 dB min. Ø Gain: 6 – 20 dBi (Size depends on Gain) Ø VSWR: 2.5:1 – 3.0:1, depends on model. Ø Connectors: SMA, N-Type, Other (Per Request, refer to table NO4) Ø Material: Aluminum or Copper Ø Finish: Chromate Conversion Ø Paint: Black / White Epoxy Enamel or other per request. Ø Open Boundary Horn Antennas are available.
