Rfaxis Inc. reports that its RFX2402 RF Front-end IC (RFeIC) has been designed into multiple platforms featuring the latest 802.11n 3Tx3R MIMO solutions from Ralink Technology Corp.

The device was selected for Ralink's 3x3 MIMO USB dongle RT3573 and PCIe router designs RF3883 because of its size, competitive performance and attractive price. The RFX2402 offers a complete set of RF front-end blocks needed for 802.11n Wi-Fi operations fully integrated onto a single silicon die that fits within a very compact 3 x 3mm QFN package. It also offers on-die matching and filtering to make system integration easy without having to craft inefficient external matching circuits.

The RFeIC integrates a power amplifier with +18dBm linear power for OFDM 64QAM operation, a low-noise amplifier, antenna switch, harmonic filter, power detector and all RF impedance matching and decoupling components into a single silicon chip.

The RFX2402 is priced at 20 cents for high-volume customers.
