It is well known that the relationship between … Continue reading SAGE Millimeter Doppler Radar Target Simulator
Programmable attenuators are widely used in automatic test setups to give an absolute attenuation setting for many components, sub-assemblies, and system characterizations. It is a very critical and important test equipment in the industry. The industry only has very limited offerings for waveguide programmable attenuators, especially in high millimeterwave frequency bands, such as V, E, … Continue reading SAGE Millimeter’s High Precision Programmable Attenuators
Direct reading attenuators are widely used in test labs and production lines to give an absolute attenuation setting for many components, sub-assemblies, and system characterizations. It is a very critical and important test equipment in the industry. The industry only has very limited offerings for waveguide direct reading attenuators, especially in high millimeter wave frequency … Continue reading SAGE Millimeter’s High Precision Direct Reading Attenuators
Sometimes the most challenging part of working in a busy lab environment is having the right tools to do the job. Even the act of mating two flanges can be challenging due to tight space or missing waveguide screws, misplaced screwdrivers, and too many connections. SAGE offers the industry a simple, effective, and easy-to-use contraption … Continue reading Waveguide Quick and Tight Connect
SAGE Millimeter often receives questions on measuring the axial ratio for polarizers. In this blog post, SAGE Millimeter (SAGE MM) reveals the step-by-step process of axial ratio measurement for its SAS series polarizers. A Vector Network Analyzer (VNA), Orthomode Transducer (OMT), and Mode Transition will be used to test the axial ratio. Figure 1 shows … Continue reading How is the Axial Ratio of a Polarizer Measured?
SAGE Millimeter offers microwave and millimeterwave amplifiers and active multipliers in the frequency range of 10 MHz to 170 GHz. SAGE Millimeter’s standard amplifiers and active multipliers all have built-in regulators to protect the delicate microwave semiconductor devices. In addition, all amplifier and active multipliers have a built-in “charge pump” to generate negative bias so … Continue reading Bias Clarifications of SAGE Millimeter’s Amplifiers and Multipliers
SAGE Millimeter offers two types of waveguide screws for millimeter wave product interconnections: The smart model number system that SAGE Millimeter implements indicates the hex size of these two models. SWH-332-SS requires standard 3/32 ball end hex screwdriver, while SWH-564-SS requires standard 5/64 ball end hex screwdriver when using them. The 3/32 hex size is … Continue reading Where is the 5-64 Waveguide Screw Supposed to be Used?
SAGE Millimeter offers many aperture antennas. The popular ones are: There are two common questions we often receive from our customers: Do we have 30 dB or higher gain rectangular or conical horn antennas? Do lens corrected antennas make the beamwidth narrower? In this post we will address these questions. Do we have 30 dB … Continue reading Rectangular Horns, Conical Horns, and Lens Corrected Antennas
The corner reflector is a passive device used to directly reflect radio waves back toward the emission source. Therefore, the corner reflector is a useful device for radar system calibration. In general, the corner reflector consists of mutually intersected perpendicular plates. The commonly seen corner reflectors are dihedral and trihedral. While the dihedral corner reflector is … Continue reading Corner Reflectors
