The SKY68031-11 from Skyworks is an LTE Multi-Band Front-End Module that supports LTE-M/NB-IoT transceiver platforms. It integrates the entire RF front end necessary for an LTE multi-band radio operating in low-band and mid-band frequencies, including broadband PA with bias controller, TX lowpass harmonic filter, antenna switch, and MIPI RFFE controller. In the Tx section, the PA load-line is optimized for high efficiency while simultaneously meeting 3GPP ACLR and emissions mask specifications. 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.
The SKY68031-11 operates from 699 – 915 and 1695 – 1980 MHz and delivers an output power of 23.5 dBm. It requires a DC supply voltage from 2.85 to 4.50 V and has a leakage current of 0.4 uA. The module has a 2.0 compliant MIPI® RFFE control interface. It is available in a 24-pad MCM package that measures 3.0 x 3.0 x 0.7 mm and is suitable for low-power, low-data-rate cellular IoT, half-duplex operation (HD-FDD) LTE applications. The module also supports LTE universal modem products in the 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
