Wideband Tuners allow you to see more spectrum. Having a wider viewing window means you’ll not be missing the very thing you’re aiming to see and collect. To illustrate, typical tuners like the one shown below are capable of “seeing” just 500 MHz.
The primary wideband output is centered in L-Band. The 1000 MHz Bandwidth dowconverter has an output at 1.5 GHz and the 500 MHz Bandwidth downconverter has an output at 1.0 GHz. However, we can support changes of this center frequency according to user needs at the time of the order. So let us know.
Derived from our IFAT product line, the Flex-IF engine counters the problem caused by a limited, static IF. When installed in the secondary output path, it provides the user with full IF agility, to:
- Set any IF Output Frequency, 50-2000 MHz
- Set any Bandwidth, from five selectable filters of 50, 100, 200, 500 and 1000 MHz in BW
With Flex-IF, enjoy a dynamic and fully-agile IF output, to take advantage of today’s ever more powerful digitizers, recorders and digital processors, without concern of disrupting your fielded systems.
Narrowband Output option
Another option in the secondary output path is to add a narrowband output that gives selectable bandwidths, of 50 and 100 MHz, and a tunable output frequency from 50-160 MHz in 10 MHz steps.
- Option LN: for low phase noise and higher stability
- Option INV: for a conversion sense toggle, switching between Inverted and Upright
- Option SWP: for an external trigger and “all settled” strobe output
Under the hood
For over 25 years, our company has been known throughout the microwave industry as a premier supplier of phase-locked oscillators and microwave synthesizers. Our frequency sources provide the backbone of frequency converters in the Satellite communications industry, the radio astronomy field, the military radar and surveillance sectors, and more. Our oscillators and synthesizers found in the design include our ground-breaking DS-3000 Synthesizer.

The RFT Downconverters can be controlled via the Ethernet port, using either a browser-enabled GUI or through SCPI commands. In many configurations, there is also an RS-232 port which can be accessed through a terminal application for sending and receiving communications using our SCPI command-set.
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. One is a “Master” and can either work independently or share its LOs and control signal with a second RFT that is designated as a “Slave”. The Slave unit has its own Local Oscillators and can work independently, or in Slave mode will switch to using the LOs provided by the Master.
Distributed Local Oscillators
- 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 LOs 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, 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. See the CONFIGURE tab for ordering options.
