The OM9901-51 power amplifier module (PAM) is designed and optimized for 2G quad-band cellular handsets supporting user-optional control of linear RF or analog Vramp of the GMSK envelope. The low band (LB) PA transmits in the GSM850/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 output matching circuitry. The Controller supports fully programmable through the RF Front-End Mobile (FEM) Industry Processor Interface (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 technology on a multi-layer laminate substrate. The entire assembly is encapsulated with plastic over mold.
