Below is a sortable table containing our online RF matrix switch models. These models have evolved from over 30 years of designing and delivering custom RF test systems. If you can’t find a model that fits your needs, please email your requirements to our test system engineers (jfwengr@jfwindustries.com). JFW does not charge NRE’s and our pricing for custom models is in-line with our catalog models.
Whether you need a blocking or non-blocking RF matrix switch, JFW has a wide selection of RF switches and power splitters/combiners to construct a RF matrix switch to meet your requirements. Example block diagrams of blocking and non-blocking RF matrix switches are listed below the sortable table. |
Do you already have an idea of the RF functionality you require but are not sure which type of matrix switch will work best. Let our engineering staff help you out. Our test system engineers are directly available ( jfwengr@jfwindustries.com). Click the column headers to sort our online models. For your specific application, please contact JFW for assistance. |
3 X 3 Blocking RF Matrix Example | | The below schematic shows an example of a 3 X 3 blocking rf matrix. It is built with switches on both the input ports and output ports. Each output port can only be connected to a single input port. Also, each input port can only be connected to a single output port. This configuration maximizes the isolation between ports and minimizes the insertion loss of the system. If you do require an input port be connected to multiple output ports at the same time, then you need to use a Non-Blocking RF Matrix Switch which is detailed in the next example. Both schematics on this page show some connections in bold. These bolded lines help to show the difference between the two types of rf matrix switch. For a blocking matrix switch, input #1 can only be connected to a single output (as shown with the single bolded connection). | | | | 
3 X 3 Non-Blocking RF Matrix Example | | The below schematic shows an example of a 3 X 3 non-blocking rf matrix. It is built with power dividers on the inputs and switches on the outputs. Each input signal is split to all output switches. This configuration provides greater switching flexibility because you can have multiple output ports connected to the same input port at the same time. The power dividers help provide more possible connection configurations, but the power dividers also increase the insertion loss of the system. Both schematics on this page show some connections in bold. These bolded lines help to show the difference between the two types of rf matrix switch. | |
Capabilities & Options | | Custom Models | | The models listed in the above table showcase some of our standard rf matrix switches. However, most of JFW’s test system business involves custom designed models. JFW does not charge NRE’s for custom models. We encourage you to email us your specific requirement (sales@jfwindustries.com). We will respond with a ROM (rough order of magnitude) quote in 1-2 days. | | | | Remote Commands | | JFW has standard remote commands for GPIB, Ethernet, and RS-232 controlled models. The command syntax is simple and allows easy control of the RF path settings. In addition to our standard commands, JFW can also provide customer specific commands upon request. | | | | Test Software | | JFW provides a GUI test program with all Ethernet and RS-232 controlled test systems. The test software for rf matrix switches has all of the remote commands built in for easy testing. Check out our sample test programs to see for yourself. |
| Options | | Attenuators: | | Electro-mechanical (up to 18GHz) or Solid-State (up to 6GHz) | | Remote Control: | | Ethernet, RS-232, GPIB, or TTL | | Manual Control: | | Keypad and display | | Enclosures: | | Benchtop or 19", 23", 24" rack enclosures | | Supplied Power: | | AC, Dual redundant AC, or DC powered | | RF Connectors: | | BNC, TNC, SMA, N, etc. | | Impedance: | | 50 Ohm or 75 Ohm |
