- Description The SKY68031-11 is a hybrid, multi-band multi-chip RF front-end(RFFE) module supporting LTE-M/NB-IoT transceiver platforms.The module integrates the entire RF front end necessary for anLTE multi-band radio operating in low-band (5, 8, 12, 13, 14, 17,18, 19, 20, 26, 28, 85) and mid-band (1, 2, 3, 4, 25, 39, 66, 70)frequencies, including broadband PA with bias controller, TX lowpassharmonic filter, antenna switch, and MIPI RFFE controller.Tx SectionThe PA load-line is optimized for high efficiency whilesimultaneously meeting 3GPP ACLR and emissions maskspecifications with LTE up to 6 RB. An integrated LPF isimplemented to reject the PA and transceiver harmonics while atthe same time minimizing any post PA loss for an optimizedtransmit current consumption. Out-of-band emissionsperformance is emphasized by the design to be 3GPP-compliantfor low-band (5, 8, 12,13,B14, 17, 18, 19, 20, 26, 28, 85) andmid-band (1, 2, 3, 4, 25, 39, 66, 70) frequencies.TRX PathsThe four TRX ports are additional broadband ports that can beused symmetrically for either Tx or Rx operation. The TRX portscan support conventional GSM power levels.Smart BiasingFor most IoT applications, the DC-DC converter might not beavailable to control the VCC supply of the PA. With a fixed DCsupply, Smart Biasing allows for easy power control through theMIPI interface by programming reduced bias current for lowergain states. Based on the application, a set of 4 to 6 different biasconditions with specific fixed-gain steps are predefined. For eachof the steps, the transceiver output power can be adjusted tomeet the desired total output power.The key advantages of the smart biasing scheme are: • Saving current consumption during lower output power operation • Easy programming of fixed-gain steps through the MIPI interface • Reducing the required output dynamic range of the transceiverMIPI RFFE Controller InterfaceThe SKY68031-11 functional operation is fully controllable by asingle MIPI interface which is used to drive the PA in variousoptimized bias modes as well as providing band selection andcontrolling the antenna switch Tx, Rx, and band selection.-->
