3 dB 90° hybrid couplers are used to split an input signal with a 90° phase shift between output signals, or to combine two signals while maintain high isolation between them. MECA Electronics’ line ...

Abstract: The technique of tandeming two symmetric 8.34-dB directional couplers to produce a 3-dB coupler was described in 1965 by J.P. Shelton, et al.. This technique is useful because broadband 3-dB ...

Krytar is a privately owned California corporation specializing in the manufacture of ultra broadband microwave components and test equipment for both commercial and military applications.

A simple workaround for all this was an acoustic coupler, a device that played your modem’s sounds directly into a phone’s receiver without any electrical connection. Modem speeds were slow ...

A device that connects a terminal or computer to the handset of a telephone. Acoustic couplers were widely used in the days of analog telephone networks in the 1970-1990s time frame to convert the ...

Description: need for additional insulation. All optocouplers are rated for 25kV isolation voltage between the LEDs and the high voltage diode. Utilizing the photo-sensitive nature of silicon, VMI has ...

With more than half a billion channels shipped into the field, the iCoupler ® digital isolation technology is a safe, reliable and easy-to-use alternative to optocouplers. These magnetically isolated ...

This repository contains scripts that were used to conduct the analyses in “Structural-Functional Brain Network Coupling Predicts Human Cognitive Ability” coauthored by Johanna L. Popp, Jonas A.

Phase-amplitude coupling between theta and multiple gamma sub-bands is a hallmark of hippocampal activity and believed to take part in information routing. More recently, theta and gamma oscillations ...
