Broadcom’s small cell power amplifiers are fully matched power amplifiers for use in the 1.93 GHz to 1.995 GHz band (MGA-43528), 2.62 GHz to 2.69 GHz band (MGA-43728), and 925 MHz to 960 MHz band (MGA-43828). Based on Broadcom’s proprietary 0.25 μm GaAs E-pHEMT technology, the device features high linearity, gain, and power-added efficiency (PAE) with integrated power detector and shutdown functions. They are housed in a miniature 5.0 mm x 5.0 mm molded-chip-on-board (MCOB) module package. These amplifiers are ideal for use as a final stage PA for small cell base transceiver station (BST) applications.
