Converters

Universal 18-40 GHz Down-Converters

These Universal converters take RF signals from 18-40GHz and down converts them to the 3-15 GHz range. Superior phase noise LOs provide an integrated RMS phase of less than 0.5 degrees. The converter is locked to an internal 10MHz reference or can be locked to an externally supplied reference. The converter operates without fans for improved reliability and environmental sealing. Optional versions can be provided with alternative combinations of frequencies, phase noise, gain, linearity or noise figure within the same package outline.

WGS Ka Band Converters

These versatile converters meet all performance and environmental requirements for the new generation of WGS terminals. In addition, variants of the flexible design will cover both military and commercial Ka-band applications. Customization options are available for lower noise, high power, higher gain, and accurate digital attenuation control. Converters are supplied with PLDROs and waveguide filter (upconverter only). Loopback translators are also available in the same configuration to allow for complete loopback test functionality.

Power Combiners and Dividers

Millitech has developed a number of solutions for highly efficient millimeter-wave power dividing and combining. These units are ideal for power combining in cascaded arrays for commercial, military, and satellite applications. Millitech utilizes both electroforming and CNC machining techniques to achieve low insertion loss, high point-to-point isolation, and excellent phase balance. Millitech also offers a number of these units as standard products and can accommodate nearly any power combining requirements.

Solid State Power Amplifiers

Our solid-state amplifiers can be combined to generate even higher power amplifiers. For example, the custom-designed assembly shown below utilizes a 94 GHz 1 Watt source created by combining eight saturated PAs. Millitech optimally tunes the SSPAs and integrates them with a heat-sink and drivers per our customer's requirements. This configuration includes a YIG oscillator and a x6 multiplier.

Line-of-sight Communications

Millitech has over 20 years of experience developing military and commercial millimeter-wave radios for secure fixed wireless line-of-sight communications applications. Millimeter-wave radio has several advantages over its conventional microwave counterpart, such as spectrum availability. These systems have pencil-thin antenna beams due to their short wavelength resulting in high frequency reuse and security. Penetration of fog enables high up-time (5-9's) at distances of up to 1.5 km.

Typical applications include:

  • V-band/E-band/W-band radios (FCC)
  • Fiber extension (last mile)
  • Militarized radio
  • Covert wireless communications
  • High bandwidth

More than seventeen gigahertz of spectrum has been allocated in the US for millimeter-wave communications in both unlicensed (FCC part 15) and coordinated use. With such abundance of available spectrum, wireless full-duplex transport at GigE rates and higher are now practical using millimeter-wave point-to-point radios.

Millitech supports these markets in several ways:

  • Military/commercial product development
  • Complete turn-key demonstration systems
  • Custom MMW module supplier (development and production)
