Solid State Transmitters
Generals. The TV transmitter TTU 50 LD gives 50 Watts peak sync in continuous service in the whole IV-V band.
New LDMOS technology. Using the latest LDMOS technology and new PA module design, the RF amplifier is extremely rugged and exhibits excellent thermal characteristics. Linearity and ITTU performance are better than older bi-polar technology. This means an excellent transmission quality with analogue or digital operation.
Digital upgradeable. The TTU 50 transmitter is upgradeable for digital transmission. Optional kits are available for easy field digital upgrading. This reduces the cost of later upgrade to digital while providing the best quality of analogue service currently available.
Frequency-agile. Transmitter is fully broadband. The RF stage can operate on any UHF channel, selectable via a digital selector.
Advanced controller provides full front panel transmitter control capabilities and extensive metering. Standard or special remote control interface is also available.
Meets or exceeds all international standards for safety and electrical requirements.
