DESCRIPTION

    The J3040 has been designed for use under FCC Rules and Regulations parts 73 and 74. This new, broadband, 40 Watt amplifier has been designed specifically for FM Translator and broadcast 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.

    The J3040 uses a universal power supply making it ideal for use with foreign AC power. An RF transistor pair rated for 80 Watts (by the manufacturer) makes the J3040 a very rugged amplifier in the field.
    Metering is provided for: RF forward power, RF reflected power, +28V, and PA current.
