Decade TN100/1W RF Power Amplifier

About: Decade TN100/1W RF Power Amplifier

The TN-100/1W is a 1 to 110 Watt variable RF power amplifier operating in the 87.9 – 107.9 MHZ commercial FM band.  It requires 1 Watts (typ.) of RF power at the input and it is designed to increase the coverage of the FM-800 or FM-850 FM transmitters.  This makes an excellent combination perfectly suited for community radio stations, campus stations, religious stations and any application where extended coverage is needed.

• 110 Watt output power, continuous duty;
• Adjustable output power from 1 to 110 Watt in steps of 1 Watt;
• Requires approx. 1 Watt of input power;
• 87.9 to 107.9 MHz operating band: no tuning required.
• LCD display for forward and reflected power, and output power transistor temperature, voltage and current;
• This amplifier, when used in conjunction with a Decade FM exciter like our FM-800 series, 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 input 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 73 and Industry Canada BETS-6 certified when used with a Decade FM-800 or FM-850 transmitter ;
• 2 years warranty;
• Manufactured in Italy
