Also, the upper layer 12 may have its lower surface 20 metalized to provide the ground plane The conductive top cover 11 and conductive bottom cover 10 provide the ground reference for the air dielectric stripline edge coupler Looks like our calculator wasn't all that accurate in this case, but we will look into this further. Ceramic may exhibit a dielectric constant of 10 to This structure provides low loss, but does not readily allow for a high performance loose directional coupler design. This substrate carries an upper conductor and a lower conductor which are interconnected together by suitable vias so that the two conductors are at the same electrical potential.

An air dielectric may be effectively achieved by employing a suspended substrate. A method for constructing a directional coupler, comprising: The vias 64, as is well known in the art, take the form of conductive plated through holes in layer This may be assisted by providing a pressurized source of air and connecting it to a suitable inlet passage 80 in layer 12 so that air may flow into the chamber 50 and thence longitudinally along the upper trace 60 and exit as through an exit passageway An improved device for coupling suspended stripline and NRD guides as claimed in claim 1 , wherein said dielectric strip is placed at said predetermined distance from said suspended stripline for minimizing insertion loss. Typically, this gap between filter sections may vary between three to twelve mils. Ground planes 30 and 32 are also electrically interconnected together by vias 70 and

This is because of the relative low dielectric constant of the teflon, on the order of two or three. It is a type of noise caused by mutual capacity and mutual impedance between signal lines.
Figure 2 shows the sectional view of the simulation model. Leave this field blank. Contact Supplier Have a question? Therefore, in the simulation model, the ratio between line width and the height of image plane is kept 1. The channels in the top and bottom plates 3. The interference current 2 and 3 are crosstalk signal decoupled from the emission line to the receiving line by the driving signal. Test fixtures Model No.
