The RFX2411 architecture integrates the PA, LNA, transmit and receive switching circuitry, the associated matching network, a harmonic filter, and a diversity switch all in a CMOS single-chip device. It also includes a bypass mode to provide maximal level of flexibility for system implementations. This RFeIC is designed for use in 2.4 GHz ISM band and supports the 802.15.4 and ZigBee standard. Typical high-power applications include home and industrial automation, smart power, and RF4CE, and others. Combining superior performance, high sensitivity and efficiency, low noise, small form factor, and low cost, the RFX2411 is the perfect solution for applications requiring extended range and bandwidth. The RFX2411 has simple and low-voltage CMOS control logic, and requires minimal external components for system implementation. The PA power detect circuit is also integrated.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. All maximum RF input power ratings assume 50 Ω terminal impedance. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Table 3.
