      1. Introduction
          In the field of electronics, we come across various types of connectors. They play an important part in the functioning of the electronic system, as they are the point of contact through which a signal enters or leaves the system. These connectors are either a part of the chassis consisting of the electronic circuit or constructed at the ends of a cable connecting two such electronic circuit system.

          What are these connectors, why there are different types of connectors, what are their characteristics? This article aims to explore the topic of interconnect system or connectors, and to understand the different aspect of this interesting subject. To begin with the discussion on connectors, it becomes necessary to provide a brief introduction of connectors.

      2. What is a connector?

          A connector is essentially a point of transition for a signal, in the sense that it travels through this junction to another point in the system. This could be a point where a connector is located, through which the signal leaves an electronic circuit and arrives at an antenna to be transmitted into the space or vice versa. The basic purpose of a connector is to transport a signal but at the same time it is required that it should not make the signal noisy or cause reflections due to this discontinuity.

          A poor connector in a system can distort a signal or lower the signal strength or cause it to radiate etc. Even the material used for connector construction (metal strength, metal type, dielectric material used etc) of a connector plays a role in determining the intended application (space, satellite, military, commercial etc) and its successful implementation. Recently, a satellite mission failed due to the on-board connectors breaking off. Therefore, it is important to select the right connector or the right Interconnect System for the required application and operating frequency.
