`
`Frequency translation and applications of the same are
`described herein, including RF modem and wireless local
`area network (WLAN) applications. In embodiments, the
`WLAN invention includes an antenna, an LNA/PA module,
`a receiver, a transmitter, a control signal generator, a
`demodulation/modulation facilitation module, and a MAC
`interface. The WLAN receiver includes at least one univer-
`sal frequency translation module that frequency down-
`converts a received EM signal. In embodiments, the UFT
`based receiver is configured in a multi-phase embodiment to
`reduce or eliminate re-radiation that is caused by DC offset.
`The WLAN transmitter includes at least one universal
`frequency translation module that frequency up-converts a
`baseband signal in preparation for transmission over the
`wireless LAN. In embodiments, the UFT based transmitter
`is configured in a differential and multi-phase embodiment
`to reduce carrier insertion and spectral growth.
