Datasheet
Figure 1-2 Hardware functional block diagram
The circuitry of the EM770W consists of three sections: baseband section, RF
section, and PM section.
l The baseband section includes the baseband processor and SDRAM/flash MCP.
It implements baseband signals processing, wireless protocols, and
management of various peripheral devices.
l The RF section includes the RF transceiver, PA, antenna switches, duplexer,
and antenna interfaces, and it supports receive diversity.
l The PMU section includes PM IC and DC-DC circuits, providing the power
supply and power management for the whole module.
1.3.2 External Hardware Interfaces
1. Antenna interface
The EM770W has a main antenna connector and an auxiliary antenna connector.
