CB2401

DESCRIPTION

The CB2401 is a fully integrated, single-chip, single-die RF Front-end Integrated Circuit. which incorporates all the RF 

functionality needed for IEEE 802.15.4/ZigBee, wireless sensor network, and any other wireless systems in the 2.4GHz ISM 

band. The CB2401 architecture integrates the PA, LNA, Transmit and Receive switching circuitry, the associated matching 

network, and the harmonic filter all in a CMOS single-chip device. 

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, CB2401 is the perfect solution 

for applications requiring extended range and bandwidth. CB2401 has simple and low-voltage CMOS control logic, and requires 

minimal external components for system implementation.
