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 appli-
cations. 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.
