1. Introduzione
L'amplificatore lineare BLA 1000 è un amplificatore lineare ad alte prestazioni costruito per
l'uso con tutti i ricetrasmettitori HF in tutti i modi di trasmissione.
Questo amplificatore usa due MosFets MRF157 configurati in classe AB2.
Opera in tutte le bande da 160 (1,8 MHz) a 6 (52 MHz) metri in maniera lineare e senza
interruzioni da 1,5 e 30MHz e da 48 a 55 MHz.
Una ventilazione forzata interna a velocità variabile provvede al raffreddamento di tutte le
parti dell'amplificatore, un circuito elettronico pilotato dal microprocessore ne controlla il
funzionamento.
Due ampi strumenti interni analogici ed un display LCD, vi tengono sempre informati sui
parametri vitali dell'amplificatore, Potenza d'uscita, Potenza riflessa, Corrente di drain,
Tensione di drain, Livello ALC e molti altri parametri sono visualizzabili per avere sotto
controllo ogni momento lo stato di funzionamento dell'amplificatore.
Vi raccomandiamo la lettura del presente manuale in tutte le sue parti prima della messa
in funzione dell'amplificatore.
Conoscere il funzionamento di tutte le sezioni dell'amplificatore vi permetterà un uso più
performante ed eviterà errori che oltre a causare una perdita di potenza d'uscita potrebbe
causare danni ai componenti anche in maniera irreversibile.
Un uso attento e corretto vi farà apprezzare le "performance" del BLA 1000 per molti anni
senza nessun intervento tecnico.
Introduction
The BLA 1000 Linear Amplifier is a high performance amplifier designed for use with all HF
transceivers and all modes of transmission.
The amplifier uses 2 MRF157 MosFets configured for Class AB2 operation.
Operation is possible for all bands from 160 (1.8MHz) to 6 (52MHz) meters and without
interruption from 1.5 to 30 MHz and from 48 to 55 MHz.
It features microprocessor controlled variable speed forced air ventilation that provides
cooling for all areas of the amplifier.
Two large analogue meters and an LCD display show all of the amplifiers operational
parameters; Output power, Reflected power, Drain current, Drain voltage, ALC level, and
other parameters, enabling the operator to see the state of the amplifier at any time. This
allows the user to obtain the maximum performance and avoid any possible operating
errors resulting in a loss of output power and possible irreversible component damage.
Attention to correct operating procedure and operating the amplifier within it’s capabilities
will result in optimim performance and many years of trouble free use.
