Historically, limited CW power was available in the millimeterwave frequency range, especially in the higher frequency bands, Ka-band and above. Therefore, power handling was not a major concern for most customers, except in the case of certain dedicated high-power applications or programs in which special attention was required. As semiconductor advancement and applications of such … Continue reading Power Handling of Waveguide Power Combiner, Directional Coupler, Crossguide Coupler and Waveguide to Coax Adapter
Many customers will question SAGE Millimeter’s waveguide to coax adapter return loss performance. They will mention that their measured return loss is lower than what is on the provided datasheets or in the specifications provided in their quotes. SAGE Millimeter has noticed that these same customers often test return loss by using the “back to … Continue reading Why is There a 6 dB Correction on Measured Waveguide to Coax Adapter Return Loss Using a Back to Back Connection?
Coaxial devices are widely used in the microwave industry and are increasingly being used at millimeterwave frequencies up to 110 GHz. Because SAGE Millimeter’s products and services focus on higher microwave and millimeterwave frequencies, only miniaturized connectors will be discussed here. The following are concepts, terms and definitions that are widely used and accepted in … Continue reading The Basics of Coaxial Connectors
