(2.5 - 2.7GHz WiMAX 1x2 MIMO TX/RX RFeIC)

The RFX3012 is a fully integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates all the RF transmit and receive functionality needed for WiMAX wireless communications. The RFX3012 architecture integrates the PA, LNA, Transmit and Receive switching circuitry, the associated matching network, step attenuators in the transmit and receive chain, and a harmonic filter all in a BiCMOS single-chip device. This RFeIC is designed for use in the 802.16e.2005 portable and mobile WiMAX applications operating at 2.5 - 2.7GHz. Combining superior performance, high sensitivity and efficiency, low noise, small form factor, and low cost, RFX3012 is a highly integrated ideal solution for 1x2 MIMO antenna applications. The RFX3012 requires minimal external components including the external power supply bypass and the desired band-pass filters needed for system performance. The PA power detect circuit is also integrated.
