The FX5820C 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 quad-band GSM/GPRS/EDGE(GSM850/EGSM900/DCS1800/PCS1900) and dual-band TD-SCDMA/TDD-LTE/5G-NR(Bands 39 & 34) application. The FEM also supports UMTS/LTE applications through 15 high linearity TRx ports.

The FX5820C consists of a GaAs HBT power amplifier, a SOI SP7T, a SOI SP10T antenna switch, and a CMOS controller chip. With delicately designed internal low-pass filters,this module provides excellent harmonic suppressions in all operating frequencies. The TRx ports are partitioned into dual independent switch blocks, comprising 6 LB ports and 9 M/HB ports. Each switch block includes an integrated directional coupler that may be monitored on the CPL port . The FX5820C also guarantees robust 8kV high ESD protection for the antenna port.

Housed in a compact 5.5mmx5.5mmx0.75mm package, the FX5820C greatly lowers the front-end complexity of multi-mode GSM/GPRS/EDGE/TD-SCDMA/TDD-LTE/5G-NR solution, facilitates the customer's implementation, and saves board room and cost significantly.
