CB2402

DESCRIPTION

The CB2402 is a fully integrated, single-chip, single die RF Front-end Integrated Circuit. which incorporates all the RF 

functionality needed for today’s wireless communications. 

The CB2402 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. The CB2402 is designed for use in 802.11b/g/n applications operating 

at 2.4GHz. Combining superior performance, high sensitivity and efficiency, low noise, small form factor, and low cost, the 

CB2402 is the ideal solution for single antenna applications, and the ideal building block for MIMO applications. 

CB2402 has simple and low-voltage CMOS control logic, and requires minimal external components for system implementation. 

The PA power detector circuit is also integrated.
