Abstract: RF near field coupling systems offer the potential for very small coil area with high efficiency. However, little previous effort has been made in quantifying the various sources of loss in ...

The HN coaxial interface is a high-voltage version of the N interface and is used in specialized applications. August 24, 2010 - RF directional couplers are readily available with common interfaces ...

Abstract: Recent RFID systems start attaching a tag array consisting of two or more tags on an object to deal with polarization mismatch and RF phase periodicity for battery-free sensing and ...

[B Arnold] is hearing voices and needs help from the Hackaday community. But before any of you armchair psychiatrists run off to WebMD, rest assured that [B Arnold] suffers not from schizophrenia but ...

Wireless system-on-chip (SoC) designs require implementing all circuit domains on the same die. This enables manufacturers to reduce cost and support integrity. On ...

Trimmed for specialized tasks, the HN RF directional coupler integrates some uncommon interfaces such as the HN female. Trimmed for specialized tasks, the HN RF directional coupler integrates some ...

A scattering matrix (or S parameter matrix) can be used to describe coupler performance with any passive termination. The S parameters within the matrix are measured using terminations which are equal ...

You picked up an RF directional coupler in the lab, but the ports are not labeled. What are the typical 4 ports of an RF directional coupler?

Potentials for atoms can be created by external fields acting on properties such as magnetic moment, charge, polarizability, or by oscillating fields that couple internal states. The most prominent ...
