The R&S® ZN-Z84 is a 48-port solution designed to complement the R&S ZNB network analyzer. It’s used to test multiport components for the wireless communications market in R&D and production phases. The matrix covers the 10 MHz to 8.5 GHz frequency range and can be controlled and operated directly from the ZNB network analyzer.
A non-blocking RF switch matrix is more complex than the blocking type, but it’s also more flexible. In this configuration, an input can be switched to multiple outputs. One input can in fact be switched to all of the outputs at once. This provides an extra degree of flexibility compared to the blocking architecture. However, a non-blocking architecture still has the limitation of not allowing two or more inputs to be switched to the same output. Input 1 for example can be simultaneously switched to every output or selectively switched to several outputs at once, but no other input can be switched to any of the same outputs.
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).
