MEDIUM POWER TV AMPLIFIER
SERIES

1.1 DESCRIPTION

The amplifier belongs to the Medium Power Amplifier products family of Television Amplifiers fully in solid
state LDMOS technology.
These TV Amplifiers operate in the UHF Band with Common amplification process (separate amplification
available) of the Video and Audio carriers. This Amplifier family has been designed to offer to the customer
high performances, high reliability and greater simplicity in its operation and maintenance procedures.
The Video and Audio signal processing is provided for all TV Standards and all types of Audio applications
(Mono & Dual Sound - NICAM) together with the different colour systems such as PAL - NTSC - SECAM.
Thanks to the amplitude and phase and non linearity pre-correction circuit, it is possible to cancel the distortions
in the output stage, thus cutting down the operating costs.
Due to the common amplification design, the transmitter is easily upgradeable to any digital TV standard:
DVB-T, DVB-H, DMB-T, ATSC. It is only necessary to replace the modulator and the RF output band pass
filter, all the other components are used without any change.
The cooling system is fully contained into the amplifier, and it is based on forced air flow. A powerful and very
low acoustic noise blower is used. A front panel air dust filter is available, sized in order to enable easy
replacement.
The user interface is based on a graphics display, where all the parameters are showed. A detailed log of
events and alarm help the maintenance of the system.
The unit can be fully controlled in REMOTE mode via PC direct-link or via PSTN, GSM or Ethernet networks
by means of Elettronika Remote Control System.
The system can be easily upgraded with dual drive option.
Besides, the transmitter can be easily integrated in a 1+1 or more complex N+1 redundancy configurations.
