RFX8422

2.4GHZ CMOS WLAN / BLUETOOTH RFEIC WITH PA, LNA WITH BYPASS & SP3T SWITCH

The RFX8422 is a fully integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates all the RF functionality needed for dual-mode WLAN, Bluetooth operations including simultaneous WLAN and Bluetooth receive capability. The RFX8422 architecture integrates a high-efficiency high-linearity PA, a directional Coupler and output Power Detector, impedance matching networks, harmonic filters, a LNA with Bypass and an SP3T Antenna Switch all in a single CMOS device.

This RFeIC is designed to be used in combined 802.11b/g/n and Bluetooth applications operating in the 2.4GHz band, and can be powered directly from the battery.

Combining superior performance, ultra-low power consumption, small form factor, and low cost, RFX8422 is the perfect solution for mobile, handheld, and portable devices with integrated WLAN and Bluetooth. RFX8422 is assembled in ultra-compact 2.5 x 2.5 x 0.45 mm 16L QFN package, and requires minimal external components and PCB footprint.

Please note: RFX8422 is being discontinued and is not recommended for new designs.
