Skyworks Solutions Inc. SKY68031-11 Multi-Band RF IoT Front-End Module

Skyworks Solutions Inc. SKY68031-11 Multi-Band RF IoT Front-End Module is a low-profile, multi-band RF front-end (RFFE) module supporting LTE-M/NB-IoT 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, 85) and mid-band (1, 2, 3, 4, 25, 39, 66, 70) frequencies. This feature includes broadband PA with bias controller, TX low-pass harmonic filter, antenna switch, and MIPI RFFE controller.

The Skyworks Solutions SKY68031-11 PA load-line is optimized for high efficiency while simultaneously meeting 3GPP ACLR, and emissions 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, B14, 17, 18, 19, 20, 26, 28, 85) and mid-band (1, 2, 3, 4, 25, 39, 66, 70) frequencies.
