Fullband mm-Wave Circulators Are on the Horizon Diving into Revolutionary Circulator Developments Circulators are useful in transmit/receive systems, isolating a transmitter from a receiver while allowing them to share a common antenna. For more than 50 years the Y-junction circulator has been the primary implementation at mm-wave frequencies. Commercial Y-junction circulators with full waveguide band [...]
Revolutionizing MMW Systems: The Crucial Role of Cryogenic Isolators Millimeter wave engineers operate in a part of the electromagnetic spectrum where there are some significant challenges to overcome. It is difficult to generate signal power, the available components are costly and sometimes don’t work well, and often the components just don’t exist at these frequencies. [...]
Two Methods for Realizing Millimeter Wave Isolators There are two fundamentally different techniques for designing isolators at millimeter-wave (MMW) frequencies. Maybe you have noticed this if you ever wondered why some isolators are narrow-band and some operate across the full waveguide band. Or maybe you noticed that some isolators are built with a terminated third [...]
Some Interesting Facts about Rectangular Waveguides David W. Porterfield, Ph.D., Micro Harmonics Corporation Rectangular waveguides are commonly used in mm-wave applications primarily because they are the lowest loss transmission media at these frequencies. They are single-moded over broad bandwidths and provide isolation from external RF signals. In this post, we will review some other interesting [...]
