OM8443-25 is a hybrid multimode multiband (MMMB) Power Amplifier Module (PAM) that supports 3G/4G/5G handsets and operates efficiently in CDMA, WCDMA, TD-SCDMA, LTE and 5G NR modes. The module is fully programmable through a Mobile Industry Processor Interface (MIPI).
The PAM consists of a 3G/4G/5G PA blocks for low, high, and mid-bands, and a Multi-Function Control (MFC) block, RF input/output ports internally matched to 50 ohm to reduce the number of external components. A CMOS integrated circuit uses standard MIPI controls to provide the internal MFC interface and operation. Extremely low leakage current maximizes handset standby time. The devices packaged in a small LGA package. (4.0 mm x 6.8 mm x 0.72 mm)
• Two T/R (RX) ports and 14 outputs
• Support 5G NR Power Class 3 operation with 3.4V Vcc supply.
• Dual Low Band RF inputs support separate transceiver outputs or interstage filtering
• Industry-leading PAE for 3G/4G/5G, Optimized for APT operation
• Fully programmable Mobile Industry Processor Interface (MIPI)
• MIPI programmable bias modes optimize best efficiency / linearity trade-off for 3G/4G/5G; minimizes DG09 for 3G.
• Ultra low harmonics leakage from LB TX ports to MB TX ports, suitable for downlink carrier aggregation
• Small package: 4.0 mm ×6.8 mm ×0.73 mm, LGA 42 pad configuration
