Product Description
The OM8816-62 is a high-power, high-efficiency Front-End Module for GSM850 / EGSM900, DCS1800 and PCS1900 operation. The FEM supports Class12 General Packet Radio Service (GPRS), EDGE multi-slot operation, and dual band TD-SCDMA / TD-LTE linear transmission. This FEM builds upon OnMicro’s unique power amplifier architecture technology to provide maximum efficiency and output power, integrated over-current and over-voltage regulating technology stable ruggedness and TRP performance under load mismatch.
The module provides 50 Ω impedance at input and output ports, consists of a CMOS Controller, a SP16T RF switch with integrated Tx low pass harmonic filtering can achieve best harmonic performance. The OM8816-62 supports both the linear-GMSK operation standard and VRAMP-BASED operation facilitating various platforms application implementation.
This FEM can sustain 8KV ESD at Antenna port, without external components needed, and also guarantee robust 12:1 VSWR on Antenna Port under load mismatch condition.
