Product Description

HS8443-71 is a hybrid multimode multiband (MMMB) Power Amplifier Module (PAM) that supports 3G/4G handsets and operates efficiently in CDMA, WCDMA, TD-SCDMA, and LTE modes. The module is fully programmable through a Mobile Industry Processor Interface (MIPI). 

The PAM consists of a 3G/4G 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 device is packaged in a small LGA package. (4.0 mm x 6.8 mm x 0.85 mm)

Product Features

        • Two T/R (RX) ports and 14 outputs

        • Industry-leading PAE for 3G/4G

        • Optimized for APT DCDC operation

        • Dual Low Band RF inputs support separate transceiver outputs or interstage filtering

        • Fully programmable Mobile Industry Processor Interface (MIPI) control

        • MIPI programmable bias modes optimize best efficiency / linearity trade-off for 3G and 4G; minimizes DG09 for 3G.

        • Small package: 4.0 mm × 6.8 mm × 0.85 mm, Max LGA 42 pad configuration.
