3. TECHNICAL BRIEF
3.2.2.1 Polar Loop Structure
Three main functions are identified in the transmitter architecture; I/Q vector modulation at IF frequency,
amplitude and phase loop at IF/RF frequencies and power amplification.
3.2.4 Front End Module Specification
3.2.4.1 Block Diagram and Internal Matching Condition
3.2.3 RF Synthesizer
3.2.4.1.1 GD330
FEM
The B6PLE integrates Front End Module control (FEM control). Word 6-12 is assigned for trigger of control
signal from B6PLE. FEMC1 and FEMC2 are interface between B6PLE and FEM. The combination of output is
decoded from word 1. FEMC1 and FEMC2 are assigned for Low and High band respectively.
