Developed in a very low profile (0.8 mm) and pact form factor, the FEM supports Class 12 General Packet Radio Service (GPRS), EDGE multi-slot operation, and TD-SCDMA and TDD LTE linear transmission. Eight transmit / receive (TRx) ports and an integrated directional coupler enables broadband 3G/4G RF switch-through. The module consists of a CMOS Power Amplifier (PA) Controller, a low band (LB) PA block supporting GSM850/900 bands, a high band (HB) PA block supporting DCS1800/PCS1900, TD-SCDMA bands 34/39, and TDD LTE band 39, input and output ports internally matched to 50 ohm impedance loads, Tx harmonic filtering, RF switching, and a directional coupler at the antenna output. The custom low-current PA controller includes the Mobile Industry Processor Interface (MIPI) and decoder circuitry to control the RF switch. Internal matching of all RF ports to a 50 ohm load reduces the number of external ponents on the phone...
