DESCRIPTION
The RFX2411 is a fully integrated, single-chip, single-die
RFeIC (RF Front-end Integrated Circuit) which incorporates
all the RF functionality needed for wireless ZigBee / smart
energy applications. 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 2.4GHz ISM band and
supports the 802.15.4 and ZigBee standard. Typical high
power applications include home and industrial automation,
smart power, and RF4CE among others. Combining superior
performance, high sensitivity and efficiency, low noise, small
form factor, and low cost, RFX2411 is the perfect solution for
applications requiring extended range and bandwidth.
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.
