Where is the 5-64 Waveguide Screw Supposed to be Used?

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?

Rectangular Horns, Conical Horns, and Lens Corrected Antennas

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

Corner Reflectors

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

Duplexing: Circulator or Orthomode Transducer?

In communication and radar systems, duplexing is one of the essential functions that allows a single antenna to perform the transmission and receiving tasks at same time. Both circulators and orthomode transducers (OMT) can play this role. The question is: Which device will the designers pick? The circulator is a ferrite based non-reciprocal device. The … Continue reading Duplexing: Circulator or Orthomode Transducer?
