The SKY68020-11 is a hybrid, multi-band multi-chip RF front-end (RFFE) module supporting cellular LTE-M/NB-IoT (half-duplex system) transceiver platforms. The module integrates the entire RF front end necessary for an LTE multi-band radio operating in low-band (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, 71, and 85), and mid-band (1, 2, 3, 4, 25, 39, 66, and 70) frequencies, including Rx low-pass filters, broadband PA with bias controller, Tx low-pass harmonic filter, antenna switch, and MIPI RFFE controller.

Tx Section
The PA load-line is optimized for high efficiency while simultaneously meeting 3GPP ACLR and missions mask specifications with LTE up to 6 RB. An integrated LPF is implemented to reject the PA and transceiver harmonics while at the same time minimizing any post PA loss for an optimized transmit current consumption. Out-of-band emissions performance is emphasized by the design to be 3GPP-compliant for low-band (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, 71, and 85), and mid-band (1, 2, 3, 4, 25, 39, 66, and 70) frequencies.
