RTM7916-51 Datasheet | UNISOC

Description 1 General Description The RTM7916-51 Transmit/Receive Front End Module (FEM) supports Class 12 GPRS, EDGE multi-slot operation, and TD-SCDMA/TDD-LTE linear transmission. Fourteen transmit/receive (TRx) ports and an integrated directional coupler enables broadband 3G/4G RF switch-through. The module consists of a CMOS controller, a low-band PA block supporting GSM850/900 bands, a high-band PA block supporting DCS1800/PCS1900, TD-SCDMA bands 34/39, and TDD-LTE band 34/39, input/output matching network, Tx harmonic filtering, RF switching, and a directional coupler at the antenna output. The lowcurrent PA controller includes the MIPI RFFE and decoder circuitry. In GMSK modes, the PA controller provides envelope amplitude control as a function of VRAMP and reduces sensitivity to input drive, temperature, power supply, and process variations. Proper timing of MIPI mands and VRAMP input ensures high isolation between the antenna and Tx-VCO while the VCO is being tuned prior to the transmit burst. In EDGE and TD-SCDMA/TDD-LTE linear modes, VRAMP voltage and MIPI-based bias settings optimize PA linearity and efficiency.
