RFX8422数据手册RF/IF射频/中频RFID的射频前端（LNA+PA）规格书PDF

描述 Description

The RFX8422 is a fully integrated, single-chip, single-die RFeIC (RFFront-end Integrated Circuit) which incorporates all the RF functionalityneeded for dual-mode WLAN, Bluetooth operations includingsimultaneous WLAN and Bluetooth receive capability.The RFX8422 architecture integrates a high-efficiency high-linearity PA,a directional Coupler and output Power Detector, impedance matchingnetworks, harmonic filters, a LNA with Bypass and an SP3T AntennaSwitch all in a single CMOS device.

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

Combining superior performance, ultra-low power consumption, smallform 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 QFNpackage, and requires minimal external components and PCB footprint.Please note: RFX8422 is being discontinued and is not recommended for new designs.
