DESCRIPTION
The RFX8422S 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 RFX8422S 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, RFX8422S is the perfect solution for mobile, handheld,
and portable devices with integrated WLAN and Bluetooth. RFX8422S is
assembled in the ultra-compact 2.5 x 2.5 x 0.45 mm 16L QFN package, and
requires minimal external components and PCB footprint.
