AUTV/2000LD

LDMOS - UHF TV AMPLIFIER

DESCRIPTION

The AUTV/2000LD is a TV amplifier that can be used in the IV/V Bd UHF . Tutti gli stadi di amplificazione
utilizzano componenti con tecnologia LDMOS, ottenendo eccellenti prestazioni in termini di guadagno e
soprattutto di linearità.
Thanks to the high-quality components used and the strong structure it can be used even in the most hostile
environments with the minimum maintenance.
It is composed by two amplifiers AUTV/1000LD coupled by means of 3dB/90° hybrid couplers ensuring an
high insulation between the apparatuses and a very good input return loss.
The amplifier AUTV/2000LD has been designed using advanced technologies made for broadcasting appli­cations. All of its components have been tested with thermic shocks in order to obtain a very high reliability
and an high MTBF .
A microprocessor control unit controls the apparatus, checking the thermic, electric and RF parameters,
intervening in case of problems and showing the whole functioning status on a large LCD display .
The purity of the spectrum is ensured by a band-pass filter which removes all the out-of-band spurious
emissions far beyond the level required by the regulations.
The transmitter is provided with linearity pre-corrector to compensate the distortions of the final stage.

1.1 FUNCTIONS

The control system is made up by some “Slave” boards, which check locally the amplifier modules,
and a “Master” board to monitor the status of the Slave boards in each module and show on a graphic
display all the checked parameters. The number of the Slaves changes depending on the output power of
the amplifier. The communication between Master and Slaves is made via I2Cbus standard. The Master
board reads the overall parameters of the equipment (forward and reflected power and unbalancing),
polls (interrogates in sequence) the local boards, shows on the display the values requested by the user
and indicates alarm conditions, if any. Besides it realizes a serial data interface to an external system
able to analyse the working parameters of the equipment, using the RS232 and RS485 communication
protocols.
At start-up, the display of the Amplifier Control shows an informational message concerning the equip­ment and the firmware version.
The main menu has: a list of the amplifier modules, the measure of some parameters of the powers in antenna,
a window with icons to show the alarm status and some general information, that is date, time, temperature
inside the module and, for FM equipment, transmission frequency .
In the Amplifier List, next to each module, you can find the following symbols:
