OM9288-11 is a multi-mode, high efficiency Mid Band and High Band L-PAMiD (LNA plus Power Amplifier Module with integrated Duplexers) module designed for use as the integrated RF front-end in multi-mode NR / LTE / UMTS / CDMA mobile cellular equipment. The high efficiency L-PAMiD contains power amplifier paths and LNA bank for 3G/4G/5G Mid and High Band frequencies along with distribution switches, multiplex filters, and antenna switches for multi-band coverage of both transmit and receive functions. OM9288-11 band select, LNA gain and operating parameters are programmed through the Mobile Industry Processor Interface (MIPI) bus(es). The OM9288-11 transmit-receive module supports Average Power Tracking (APT) and Envelope Tracking (ET) for application versatility combined with higher system efficiency across a wide range of power levels. The OM9288-11 is packaged in a RoHS-compliant, compact 62-pin, 6.5 × 8.6 × 0.79 mm surface-mount leadless package.
