Solid State Amplifiers
Generals. The TV amplifier TAU 20000 LD gives 20000 Watts peak sync in continuous service. It is suitable for analog or digital TV broadcasting in the IV/V band.
New LDMOS technology. Using the latest LDMOS technology and new PA module design, the RF amplifiers are extremely rugged and exhibit excellent thermal characteristics. Linearity and IMD performance are better than older bi-polar technology. This means an excellent transmission quality with analogue or digital operation.
Modular assembly. Easy removable identical and interchangeable power amplifier modules and power supplies reduce spare requirement and service costs.
On-air serviceability. Power supplies and power amplifier modules can be safely removed during operation, for on-air maintenance. Failure or module removal keep always transmitter on-air.
High redundancy. High on-air reliability is assured by using multiple power amplifier modules, each comprised of two individual PA’s, with independent power supplies and optional dual exciters.
Low maintenance. The overall operating costs are reduced and the maintenance is optimised for two year intervals thanks to the absence of wear-out mechanism in solid state devices.
Advanced controller provides full front panel transmitter control capabilities and extensive metering of individual modules. Standard or special remote control interface is also available.
Meets
or exceeds all international standards for safety and electrical
requirements.
