Skyworks Solutions SKY68031-11 multiband RF IoT front-end module

The SKY68031-11 multiband RF IoT front-end module, from Skyworks Solutions, supports LTE-M and NB-IoT transceiver platforms, offering output power up to +23.5 dBm optimised to support LTE for 1 RB to 6 RB.

The low-profile module integrates the entire RF front end necessary for an LTE multiband 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 a broadband power amplifier (PA) with bias controller, transmit low-pass harmonic filter, antenna switch and MIPI RFFE controller.

The module’s PA load-line is optimised for high efficiency while simultaneously meeting 3GPP ACLR and emissions mask specifications with LTE up to 6 RB. The integrated low-pass filter rejects the PA and transceiver harmonics while at the same time minimising any post-PA loss for an optimised transmit current consumption. Out-of-band emissions performance is emphasised by the design to be 3GPP-compliant for low-band and mid-band frequencies.
