MXi201V TECHNICAL SERVICE MANUAL
1 MXi201V AMPLIFIER–INTRODUCTION
This Technical Service Manual contains publications (PUBs) describing the technical details of the MXi201V
amplifier, as well as the overall operating instructions, including the bench test procedures of the amplifier stages
incorporated in this unit. It also covers the transmitter’s start-up operation, and troubleshooting, as well as basic
transmitter maintenance guidelines.
The RF section of the MXi201V Amplifier consists of a heatsink assembly that includes five cascaded broadband
amplifier modules and a splitter and combiner and a directional coupler.
Figure 1 shows the layout of this
assembly.
