A Guide to RF Switching Systems

Whether you are designing an RF switching system or planning to purchase one, it is important to understand the fundamentals of these complex systems and the ways in which application requirements impact cost and performance. In order to understand the challenges in a matrix design, it is important to understand the critical building blocks, as well as the important decisions that must be made along the way. This paper explains the requirements placed on switching systems and the tradeoffs that different choices will present.

Design Guide Microwave Switches & RF Coaxial Relays

A guide in basic microwave theory and its application in microwave switches and RF coaxial relays.

CANbus Controlled Switch Matrices

Electronic control of conventional buses such as RS-232, RS-422 and GPIB, requires complex wiring for control and power lines in electromechanical switch matrices. As these switches grow in complexity, the control interconnections between components become a real challenge, thus increasing design and integration time and affecting serviceability. This paper features how Controller Area Network (CAN) resolves the complexity in designing electromechanical switches matrices.

Smart Switches with CAN Serial Communication Bus

A series of electromechanically switches are developed that is targeted specifically at test equipment applications. The unique switches are based on ISO defined serial communication bus which adds tremendous flexibility to today’s complex test systems. This paper will discuss in details how these switches operate.
