MXI1002 OPERATIONS AND MAINTENANCE
1 THE MXi1002 TRANSMITTER
The MXi1002 transmitter is usually comprised of a LARCAN Modulator, a Power supply chassis, and two
Amplifier chassis.
The RF section of the MXi1002U consists of two identical amplifiers configured to operate in quadrature. Each
amplifier is capable of delivering power over 500 Watts Average Digital Power. The output of these amplifiers is
fed into a two-way combiner assembly with associated RF detectors which are used for protection and metering
purposes. Therefore, in this configuration, the MXi1002 is capable of delivering RF power of up to 1kW Average
Digital Power with exceptional performance and reliability.
The power supply chassis (top unit shown in Fig.1) contains the main controller board, LCD display, two high
efficiency +50VDC switching power supplies and two +12VDC switching power supplies. The +12VDC power
supply provides power to the controllers, and the +50V supplies power to the amplifiers.
