Multi-band RF IoT front-end module optimised for high efficiency

Mouser now stocks the SKY68031-11 multi-band RF IoT front-end module from Skyworks Solutions. The low-profile module supports LTE-M and NB-IoT transceiver platforms, providing output power up to +23.5dBm optimised to support LTE for 1RB to 6RB.

The module integrates the complete RF front end required 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 incorporates a broadband 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 fulfilling 3GPP ACLR, and emissions mask specifications with LTE up to 6RB. The integrated low-pass filter rejects the PA and transceiver harmonics whilst at the same time reducing any post-PA loss for an optimised transmit current consumption. The design emphasises out-of-band emissions performance to be 3GPP-compliant for low-band and mid-band frequencies.
