Pure-CMOS dual-mode Wi-Fi/Bluetooth RF front-end IC for mobile applications

May 21, 2012 // By Jean-Pierre Joosting
RFaxis offers its RFX5000 RF front-end integrated circuit (RFeIC™) to enable wireless connectivity for next-generation 802.11a/n/p wireless connectivity applications in the 5 GHz band.

The technology supports PCs, ultra-mobile devices, high definition multimedia streaming devices, routers/access points, as well as wireless access in vehicular environments (WAVE).

The RFX5000 RFeIC is a single-chip/single-die, integrated RF front-end on pure complementary metal oxide semiconductor (CMOS) silicon and covers the 802.11a/n/p frequency band (4.90 to 5.95 GHz). The RFeIC comes with a power amplifier, low noise amplifier, antenna switch, on-chip harmonic filters, power detection, matching circuitry, CMOS compatible control logic and ESD protection on all package pins.

Key specifications include 30 dB Tx and 12 dB Rx small=signal gain, 120 mA quiescent current, 2.7 dB noise figure, and +17 dBm linear output power (EVM <3%). The RFX5000 RFeIC is available in a standard 3- x 3- x 0.55-mm QFN package.
