描述 Description

OM9085-11 is multi-mode multi-band Tx-Rx Front-End Module (FEM) supports 2G / 3G / 4G mobile devices and operates efficiently in 3G/4G modes. The FEM consists of a low-band 3G/4G PA block, low- and high-band 2G PA blocks, a silicon controller containing the MIPI RFFE interface, RF band switches, antenna switches, a bi-directional coupler, and integrated filters for Bands 8, 12, 20 and 26. Extremely low leakage current maximizes device standby time.The IC die and passive components are mounted on a multi-layer laminate substrate. The assembly encapsulated in a 7.6 mm x 6.0 mm x 0.80 mm, 56-pad MCM, SMT plastic package allows a highly manufacturable, low cost solution.The 9085-11 FEM is optimized for LTE Advanced which utilizes Carrier Aggregation for higher data rates. The combined filtering, RF matching, and TRx switching internal to the FEM optimizes performance for popular Downlink (DL) CA band combinations, all in a compact and low cost solution. The FEM contains necessary components between the antenna and RFIC transceiver and is optimized to provide superior Rx sensitivity and Tx efficiency. Selecting the linear-GMSK operation standard disables VRAMP input, so all PA biasing depends only on MIPI mode selection. The transmitted envelope is then a linear function of RF input. Selecting VRAMP-enabled operation, the PA controller provides VRAMP control of the GMSK envelope and reduces sensitivity to input drive, temperature, power supply, and process variations. In EDGE linear mode, VRAMP voltage and MIPI-based bias settings jointly optimize PA linearity and efficiency. Exceptional RF coexistence planning and system techniques are employed to minimize Rx de-sensitizing (\"de-sense\").Product Features► MIPI® RFFE 2.0 control interfaces w/ 1.8 V nominal supply► Integrated switched duplexer filters for Bands 8, 12, 20 and 26► Four auxiliary 3G/4G Tx outputs for external filters► Four auxiliary 3G/4G TRx ports to support additional bands► Tx filtering for harmonically-related LB-MB downlink CA► Integrated low band and high band 2G PAs► High band 2G works with companion MB/HB modules► Integrated bi-directional RF coupler with cascade support► Small, low profile package:        • 7.6 mm x 6.0 mm x 0.80 mm        • 56-pad configurationApplications► Multi-band 2G / 3G / 4G Mobile Devices► Handsets, Data Cards, M2M► LTE Advanced Carrier Aggregation (CA)► WCDMA, HSPA+► CDMA2000 1x RC1, RC3, EVDO (Rev A)► FDD LTE► Uplink QPSK, 16QAM, 64QAM► Critical L+M, L+H Downlink CA support Functional Block Diagram
