The FX5805A is a multi-mode multi-band front-end module (FEM) delivering both the power amplification and antenna switching functions. With the state-of-the-art integration design and advanced GaAs technology, this FEM supports both quad-band GSM/GPRS/EDGE (GSM850/EGSM900/DCS1800/PCS1900) and dual-band TD-SCDMA/TDD-LTE (Bands 39 & 34 1880-1920MHz and 2010-2025MHz), with matched 50-Ohm RF input and output ports. The FEM also supports UMTS/LTE applications through 16 high linearity TRx ports.
The FX5805A consists of a GaAs HBT power amplifier, a SOI SP8T, a SOI SP10T antenna switch, and a CMOS controller chip. The GaAs HBT power amplifier can work in saturated mode for GMSK, as well as in linear mode for EDGE 8PSK and TDSCDMA/TDD-LTE operations. With delicately designed internal low-pass filters, this module provides excellent harmonic suppressions in all operating frequencies. The TRx ports are partitioned into two independent switch blocks, comprising 7 LB ports and 9 MHB ports. Each switch block includes an integrated directional coupler that may be monitored on the CPL port with selectable forward or reverse directionality. A built-in diplexer provides simultaneous LB and M/HB reception required for downlink CA at the single antenna port. The FX5805A also guarantees robust 8kV high ESD protection for the antenna port.
Housed in a compact 5.5mmx5.5mmx0.75mm package, the FX5805A greatly lowers the front-end complexity of multi-mode GSM/GPRS/EDGE/TD-SCDMA/TDD_LTE solution, facilitates the customer’s implementation, and saves board room and cost significantly.
