J3100 40-100 WATT POWER AMPLIFIER (for translators or low-power FM stations)

DESCRIPTION

    The J3100 has been type accepted for use under FCC Rules and Regulations parts 73 and 74. This new, broadband, linear, 100 Watt amplifier has been designed specifically for FM Translator use as per the 1991 part 74 rule changes. However, under part 73, this unit could be used as a driver or final for a low power FM station, or as part of a low power standby equipment package.
    Temperature and reflected power values are continuously monitored to assure they conform to adjustable, preset limits. When these limits are exceeded, an externally accessible reference point is reduced to near ground potential via two diode or-gates. When the amplifier is used with one of Tepco's J-317 FM Translators, an out-of-limits condition will cause the translator to mute for the duration of the problem. The circuit will automatically reset if conditions return to normal. Specific Information on this circuit can be supplied to those wishing to interface this amplifier to other drive units.
    The J3100 uses a universal power supply making it ideal for use with foreign AC power. An RF transistor pair rated for 300 Watts (by the manufacturer) makes the J3100 a very rugged amplifier in the field.
