The D-band is the new E-band. Covering 60-90 GHz, the E-band is a well-established high-capacity solution for a number of millimeter wave applications. However, there is a growing appetite for more, and meeting that ever-increasing demand for greater data transmitted at higher speeds will require the move up to higher frequencies such as the D-band (110-170 GHz).
The problem is that currently, there is simply not enough infrastructure in place to support such a move. However, as this article (click here to download) from everything RF points out, companies like Virginia Diodes, Inc., Keysight Technologies, and Micro Harmonics Co. | an Inc. 5000 Company are making huge strides to help bridge the gap.
A Gold Rush to D-Band and Beyond (everythingrf.com)
We are honored to have been awarded the 2022 Product of the Year from Electronic Products Magazine. Our Hybrid Circulators won for “Best RF and Microwave Product.”
The patent-pending hybrid circulator is designed for wideband millimeter-wave (mmW) transmit (Tx)/receive (Rx) systems.
It combines an orthomode transducer with a Faraday rotator to achieve more than twice the bandwidth in WR-15 and an order of magnitude of the bandwidth in WR-5.1 compared with the traditional Y-junction design.
The hybrid circulator is claimed as the first to cover the 150- to 190-GHz and the 54- to 68-GHz bands with 20-dB level isolation.
