RFX2402E

CMOS 2.4GHZ TRANSMIT/RECEIVE WLAN RFeIC

The RFX2402E is a fully integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates all the RF functionality needed for today’s wireless communications.

The RFX2402E architecture integrates the PA, LNA, Transmit and Receive switching circuitry, the associated matching network, and a harmonic filter all in a CMOS single-chip device.

This RFeIC is designed for use in 802.11b/g/n/ac applications operating at 2.4GHz. Combining superior performance, high sensitivity and efficiency, low noise, small form factor, and low cost, the RFX2402E is the ideal solution for single antenna applications, and the ideal building block for MIMO applications.

The RFX2402E has simple and low-voltage CMOS control logic, and requires minimal external components for system implementation. The PA power detector circuit is also integrated.
