Dual Channel, Phase Coherent
Downconverters tunable to 40 GHz

This includes Syntonic Microwave’s RFT-3170, RFT-3180 and RFT-3190 fixed IF Tuners with 500 MHz, 1000 MHz and 2000 MHz of instantaneous BW, respectively.

When configured for Stand-Alone usage, the RFT-3100 or RFT-3200 Tuner is a full-featured microwave tuner/downconverter that requires no cabling to/from the companion tuner in order to work. It contains a full set of components and is addressable independent within the LAN.

When configured for Master/Slave mode, the RFT-3100 or RFT-3200 Tuner/Downconverter operates in pairs, where one Tuner is set-up as a Master and the second downconverter is set-up as a Slave.  An interface cable interconnects the two devices and all of the Local Oscillators (LOs) from the Master are provided via RF cabling to the Slave. Once communications between the boxes is established, the controls (either from the front panel, the ethernet port or RS-232 serial port) between the user and the Master are then communicated to the Slave.

As a result, a single investment in a pair of Tuners configured for Master/Slave enables the user to enjoy both usage models: stand-alone and paired for coherent, dual channel operations. The figure below illustrates this capability.

Frequency extension for the RF Input can be added for operations as high as 40 GHz and as low as 100 MHz.  A wide range of options can also be specified, such as conversion sense inversion, enhanced/improved phase noise and stability, ruggedized packaging for difficult environmental service conditions, AGC/MGC, and narrowband IF’s.  Wideband instantaneous BW can be specified, including 500 MHz, 1000 MHz, and now 2000 MHz.

In fact, Syntonic Microwave provides users with even more choices, including customized IF frequencies, customized input Bands and unique communication standards.  For more information about these downconverter/tuners, please refer here.
