Matrix Switches


Dow-Key Microwave, a leader in the design and manufacture of switching products, acquired its Matrix line in 1999. Since that time, the line has expanded to include both standard and custom matrices supporting the aerospace, military and communication industries for both signal routing and ATE applications.

The L-Band matrix distributes 8 L-band signals to 8 receivers in the frequency range 950 … 2150 MHz without any blocking.

Dow-Key Microwave offers a CANbus-based Coaxial Switch Matrix system with Ethernet, GPIB, RS-232, RS-485, and CANbus control interfaces. The system performs from 300 MHz to 1 GHz and is configured as an 8X8 Full Fan-Out Switch Matrix

The new wireless network surveillance system from Corry Micronics comprises the RFMS-2x8*8 8 Channel Matrix with a Probe Port and two CMIATT-4CH-200W 100 W Attenuator banks. It is capable of a range of configurations ranging from one port to over 48 ports. The 8-channel RF matrix switch is designed with a probe/test port where the signal analysis occurs. The 8-channel switch is bi-directional enabling testing in both directions. System frequencies can be customized to the end user’s specifications.

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.

Dow-Key Microwave provides a reconfigurable CANBus-based integrated switch matrix (P/N 13D12-480822T) equipped with a built-in ethernet port. This switch matrix is based on the well-established standard design of the SP12T switch with internal termination

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.

The Miniature MS-series Matrix is equipped with high performance Reliant Switches™ with 0.03 dB insertion loss repeatability across the DC to 26.5 GHz frequency range, and is ideal for test and measurement applications. The small sized enclosure can be populated on the front panel with a maximum of 8 SPDT switches, 2 SP6T switches, 1 SP6T + 4 SPDT switches, or 2 SP6T + 1 SPDT switches.
