Product Description
The HS8816-31 is a high-power, high-efficiency Front-End Module for GSM850/900, DCS1800 and PCS1900 operation. The FEM supports Class.12 General Packet Radio Service (GPRS), EDGE multi-slot operation, and TD-SCDMA linear transmission.
The module provides 50 ohm impedance at input and output ports, consists of a CMOS Controller, a SP16T RF switch, a power amplifier supporting GSM850/900, DCS1800/PCS1900, TD-SCDMA bands 34/39.The module integrated Tx low pass harmonic filtering can achieve best harmonic performance.
The HS8816-31 provides high-power and high-efficiency Pout for GSM850/900, DCS1800, PCS1900 operation mode. In EDGE and TD-SCDMA, VRAMP voltage and MIPI-based bias settings optimize PA linearity and efficiency.
