- The new R&S SZV100A RF upconverter from Rohde & Schwarz now offers a solution for testing broadband transponders in the payloads of very high throughput satellites (VHTS).
- With its 2 GHz modulation bandwidth, the R&S SZV100A covers the entire frequency range from 36 GHz to 56 GHz.
The Q/V band offers greater bandwidths for satellite feeder links. It is therefore suitable for the implementation of next-generation high-speed data links implemented by conventional geostationary satellite operators as well as those deployed in low earth orbit. Future cellular backhaul and communication networks will thus be able to transmit large volumes of data.
High demands are placed on microwave components in the Q/V band, which means they must undergo extensive testing during development and verification. Amplifiers, converters, receiver modules and complete satellite payloads are just a few examples of components that have to be tested in the Q/V band. Together with the R&S SMW200A vector signal generator, the R&S SZV100A Q/V band RF upconverter provides continuous coverage of all satellite bands from VHF to V band as well as the frequency bands for 5G in the Q/V band.
The test setup consists of the R&S SMW200A vector signal generator, the R&S SMA100B RF and microwave signal generator, and the R&S SZV100A Q/V band RF upconverter. The R&S SMW200A delivers the modulated broadband IF signal with bandwidths up to 2 GHz, while the R&S SMA100B provides the high-precision LO signal. The maximum output power of the R&S SZV100A is as high as +16 dBm (at 1 dB compression point).
The compact housing design, low weight and mounting points of the R&S SZV100A allow mounting as close as possible to the DUT, for example on the outside of a thermal vacuum chamber (TVAC). The distance between the IF source or LO source and the R&S SZV100A can be as much as 10 meters, allowing an optimized test setup.
The upconverter and the signal generators can be operated remotely with a PC software over a LAN connection. The R&S SZV remote control software enables configuration of the entire device setup.
The R&S SZV100A is ideal as a low-cost upgrade for existing test systems. Thanks to the control software, the setup consisting of the R&S SZV100A, R&S SMW200A and R&S SMA100B can be operated as a single instrument.
