Abstract: A noise canceler for use in a transceiver is disclosed. In an exemplary embodiment, an apparatus includes a split amplifier to output an amplified transmit signal, the split amplifier providing a first noise attenuation factor in a receive band. The apparatus also includes a transmit antenna to transmit the amplified transmit signal, the transmit antenna being isolated from a receive antenna by an antenna isolation factor that provides a second noise attenuation factor in the receive band. The apparatus also includes a noise canceler configured to subtract a detection signal from a received signal to obtain an adjusted received signal, wherein subtraction of the detection signal provides a third noise attenuation factor in the receive band, and wherein the first, second, and third noise attenuation factors combine to provide a selected amount of noise attenuation in the receive band.

Abstract: Transceivers implemented with a combination of super-heterodyne and zero intermediate frequency (ZIF) topologies are disclosed. In an exemplary design, an apparatus includes a frequency conversion circuit and a local oscillator (LO) generator. The LO generator generates a first LO signal and a second LO signal. The frequency conversion circuit performs frequency conversion (i) between intermediate frequency (IF) and baseband, based on the first LO signal, for an IF signal and (ii) between radio frequency (RF) and baseband, based on the second LO signal, for an RF signal. The frequency conversion circuit may perform frequency downconversion (i) from IF to baseband for a super-heterodyne receiver and (ii) from RF to baseband for a ZIF receiver. Alternatively or additionally, the frequency conversion circuit may perform frequency upconversion (i) from baseband to IF for a super-heterodyne transmitter and (ii) from baseband to RF for a ZIF transmitter.

Abstract: A wireless device with built-in self test (BIST) capability for testing/calibrating transmit and receive circuits is disclosed. In an exemplary design, an apparatus (e.g., a wireless device or an integrated circuit) includes a first circuit and a second circuit. The first circuit (e.g., a transmitter or a mixer) provides a test signal to at least one transmit path. The test signal is electro-magnetically coupled from the output of the at least one transmit path to a test signal line. For example, the test signal may be provided from the at least one transmit path via at least one antenna feed line to at least one antenna element and may be electro-magnetically coupled from the at least one antenna feed line to the test signal line. The second circuit (e.g., a buffer, a receiver, or a mixer) processes a received test signal from the test signal line.
