A super non-blocking switch matrix has the most flexible architecture, yet most complex when compared to blocking and non-blocking types. In this configuration any input can be switched to any and all outputs. In addition to this, multiple inputs can be routed to the same output. Input 1, for example, can be simultaneously switched to every output or selectively switched to several outputs at once. Input 2 can also be simultaneously switched to every output or selectively switched to several outputs at once, regardless of how Input 1 (or any other input) is routed. The same is true for all of the remaining inputs.
A blocking RF switch matrix can achieve high levels of isolation and lower levels of insertion loss because of their internal switches (which exhibit high isolation and low loss characteristics). They’re the simplest type of available RF switch matrix configurations.
Ducommun RF Products has been actively working with our individual customers to develop unique testing solutions with our Switch Matrices and coaxial switches. Ducommun RF Products has over twenty five years experience with the design and manufacturing of switch matrix systems. Combining together our technical knowledge of both coaxial switches and switching systems, we have been able to assist our customers with a variety of solution that fit their unique requirements. Ducommun RF Products offers a complete, fully supported, turnkey solution that allows our customers to have the benefit of a customized solution at a fraction of the price.
Corry Micronics’ RFMS-4X256-B is a 4 to 256 blocking RF switch matrix covering the 900-2500 MHz frequency range. It has a -8dB insertion loss, 50 ohms impedance, 10 dB return loss, +30 dBm P1dB, -80 dB isolation, and a 5µs switching speed (50% trigger to 10% RF power).
The CB-Series by Dow-Key Microwave is a crossbar matrix switch system that allows any input to be connected to any output, making it an ideal switch solution for complex test setups and signal routing.
