タイトルまたは説明

The TN***0/1W is a **0 Watts RF power amplifier operating in the *7.9 – **7.9 MHZ commercial FM band. It takes 1 Watts of RF power at the and boosts it up to **0 Watts at the output, making it perfect to increase the coverage of the FM***0 or FM***0 FM transmitters. The output power of the TN***0/1W is controlled by the output power of the FM***0 or FM***0 connected to it. This makes an excellent combination perfectly suited for community radio stations, campus stations, religious stations and any application where extended coverage is needed.

FEATURES

·         **0 Watts output power, continuous duty;

·         Adjustable output power by the means of the power (output power of the Decade FM***0 or FM***0 FM transmitter);

·          *7.9 to **7.9 MHz operating band: no tuning required.

·         This amplifier, when used in conjunction with a Decade FM exciter like our FM***0 series (which are characterized by very easy frequency programmation), is very fit to be used as a stand alone or back-up setup;

·         No maintenance required;

·         Electronic protections that guard the power transistor from damages that can be caused from accidental events like load disjunction, ventilation system's fault and overdriving;

·         Stabilized DC supply, with a wide tolerance from main voltage variations, like spikes;

·         Meets or exceeds international standards for safety and electrical specifications;

·         FCC part *3 and Industry Canada BETS*6 certified;

·         1 year warranty;

·         Manufactured in Italy
