描述 Description

The OM9901-52M power amplifier module (PAM) is designed and optimized for 2G quad-band cellularhandsetssupporting user-optional control of linear RF or analog Vramp of the GMSK envelope. The low band (LB) PA transmits in theGSM850/EGSM900 bands. The high band (HB) PA supports DCS1800/PCS1900 bands.?The compact 3.0 mm x 3.5 mm x 0.67 mm module consists of a CMOS PA including a Controller, 50 Ω input and outputmatching circuitry. The Controller supports fully programmable through the RF Front-End Mobile (FEM) Industry ProcessorInterface (RFFE MIPI) with providing PA bias and product identification read-back capability.?The power amplifier blocks, the controller and the passive components are mounted by flip-chip package technologyon a multi-layer laminate substrate. The entire assembly is encapsulated with plastic over mold.
