Our high-speed DVB Modulator-Upconverter series combines WORK Microwave’s fifth-generation upconverters with a DVB modulator in a single housing, providing operators with significant cost and space savings. No extra modulator is required. Ideal use cases include fixed satellite ground stations as well as in satellite newsgathering (SNG) vehicles, flyaways, and other mobile or portable applications.
New approach – better solution
Traditionally, two separate units are in use for highpower TV uplinks that require low spurious emissions: a modulator plus a conventional upconverter. WORK Microwave’s combined modulator and converter concept allows both units to exist in one housing. This approach provides a very low spurious signal over the whole frequency band and reduced group delay characteristics. This is a significant advantage compared with combined L-band modulator/block converters. For each frequency band the entire bandwidth range is covered e.g. for Ku-band, 12.75- 14.50GHz is supported.
MPEG transport stream input-RF output
The unit accepts MPEG transport streams on ASI, SPI, or TS over IP inputs from a video encoder or MPEG multiplexer and provides a DVB-S/S2/S2X modulated carrier in the C-, X-, Ku-, K- or Ka-band which can be directly connected to a high-power amplifier.
Additionally a baseband frame input is available for VCM and ACM operation in combination with external multiplexers or encapsulators.
