  • Page 5: Overview

    Chapter 1 THEORY OF OPERATION Overview This Chapter provides a detailed theory of operation for the power distribution and controller circuits in the radio. The components for these circuits are contained on the Main Board. Refer to the RF sections of this manual for the component location details and the parts lists for these circuits. Radio Power Distribution Accessories 20 pin Connector...

  • Page 6: Controller Circuits

    THEORY OF OPERATION Controller Circuits Controller Architecture The controller board is the central interface between the various subsystems of the radio. It is separated into MCU digital and audio/signalling architectures as shown in Figure 1-2. External Microphone To Synthesizer Internal Microphone 16.8 MHz Reference Clock...

  • Page 8: Modb/vstby Supply

    THEORY OF OPERATION A MOSFET Q416 switches in the LiO supply when Vdd is removed. Q416 also provides isolation from BOOT_CTRL function in the event of radio program flashing. The 3.3V regulator charges the Lithium battery. ModB/Vstby Supply The supply to the ModB/Vstby pin varies depending on the conditions listed in Table 1-2. Table 1-2 ModB/Vstby Supply Modes Condition Circuit Operation...
