Overview
RFX8425 is a pure CMOS-based, single-chip/single-die RFeIC (RF Front-end Integrated Circuit) that incorporates all key RF functionality needed for implementing high-performance RF front-end for WLAN IEEE 802.11b/g/n and OFDM/256QAM operation in the 2.4GHz band. The RFX8425 architecture integrates a high-efficiency high-linearity power amplifier (PA) with harmonic filter, a directional coupler based power detector, a low noise amplifier (LNA), an SP3T switch for Bluetooth antenna sharing, and an additional SPDT switch for selection between LNA and Bypass in Receive mode. All the impedance matching components and DC-block capacitors are also integrated to minimize the PCB footprint for system implementation.
RFX8425 is assembled in an ultra-compact, low-profile 2.3x2.3x0.45mm 16L QFN package. It has simple and low-voltage CMOS control logic, and requires minimal external components. Designed to work in the 3.0- 3.6V voltage range, the RFX8425 is ideal RF front-end solution for implementing 2.4GHz WLAN/BT in PC clients, tablets, and many other mobile platforms including smartphones that have a PMIC available to provide the required supply voltage for the RF front-end.
