SKY68000-31 General Description

The SKY68000-31 is a hybrid, dual-band multi-chip RF front-end(RFFE) module supporting cellular LTE-M/NB-IoT(half-duplex system) transceiver platforms. The module integratesthe entire RF front end necessary for an LTE dual-band radiooperating in Band 13 and Band 4 including Rx SAW filters,dual-band PA with bias controller, Tx low-pass harmonic 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 compliant forBand 13 and Band 4.Rx SectionReceive SAW filters are integrated in to the module along with thenecessary matching, yielding a 50 Ω single-ended impedance forthe antenna and Rx ports. The SAW filters provide a high level ofrejection to out-of-band interferers protecting the transceiver fromhigh blocking signal levels and to support 3GPP LTE blocking testconformance. The Rx SAW filters cascaded with the low throwcount switch establishes a lower insertion loss and noise figurethan conventional LTE receivers.MIPI RFFE Controller InterfaceThe SKY68000-31 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.

Key Features
