Syntonic Microwave has expanded its RFT Microwave Converters line of products to support the growing need for phase coherent operation.
We now offer three different configuration schemes to meet this need. Each of these configurations has key advantages and trade-offs.
Block diagrams for each of these configurations and usage models are provided below to help the user find the optimal solution for their particular requirement.
MASTER / SLAVE CONFIGURATION
- Each type works independently, stand alone
- Units then cable together for coherent operation
- Multiple configurations enables best versatility
- Taken together, the coherent solution is 2U high
In the Master/Slave configuration diagrammed above, there are two separate RFT’s. The “Master” works independently or can share its LOs and control signal with a second RFT. That is designated as a “Slave”. Furthermore, the Slave unit has its own LOs and can work independently. In Slave mode it will switch to using the LOs provided by the Master.
- Optimized for cases with multiple converters
- Reduced cost due to LO re-use
- Single 1RU can be configured for Dual Cvtrs
- Feed up to 6 converters from LO unit
In the configuration diagrammed above, one single 1RU chassis is outfitted with just the Local Oscillators, the front panel and ethernet interfaces and the reference system. The outputs of these local oscillators are then split and multiplexed to the rear of the chassis. The RFT Slave units, which have no local oscillators, accept their inputs from the LO unit. This configuration is very useful for applications where a large number of converters (say greater than two) need to be phase coherent with each other. Slave units without LOs have room for two converter paths each.
- Self-contained solution
- Single Box
- One set of controls
- No special cabling or interconnects
In the configuration diagrammed above, one single 1RU chassis is outfitted with dual frequency conversion paths. These are driven by a set of shared local oscillators. This way, a single box and single User Interface provide control over the entire product. This “all in one” configuration can then address either a single input/output (with the second path terminated) or the dual coherent paths can be addressed. This configuration is also limited to two RF paths.
The phase coherent configurations of Syntonic Microwave’s microwave tuners and converters shown above can be ordered as options now in any of the company’s converter products. For more details or to return to the Microwave Converters overview page, click here.
