Abstract: Shared filters used for both transmit and receive paths are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, or a circuit module) may include a filter and a switch. The filter operates as a transmit (TX) filter for a first band and as a receive (RX) filter for a second band. The filter may (i) receive and filter an output radio frequency (RF) signal when operating as the TX filter and (ii) receive and filter a received RF signal when operating as the RX filter. The switch is coupled to the filter and receives and passes the output RF signal to the filter or an input RF signal from the filter. The apparatus may further include a second filter operable as a TX filter for multiple bands and/or a third filter operable as an RX filter for multiple bands.

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: Techniques for supporting data transmission and reception on multiple bands for carrier aggregation are disclosed. In an exemplary design, an apparatus (e.g., a wireless device) includes first and second antenna interface circuits coupled to first and second antennas, respectively. The first antenna interface circuit includes a first transmit (TX) filter for a first band, which may be part of a first triplexer or duplexer. The first TX filter filters a first radio frequency (RF) signal prior to transmission via the first antenna. The second antenna interface circuit includes a second TX filter for a second band, which may be part of a second triplexer or duplexer. The second TX filter filters a second RF signal prior to transmission via the second antenna. The first and second RF signals may be transmitted simultaneously on the first and second bands for carrier aggregation.

Abstract: Disclosed is a telephone system using a telephone network interface configured to couple a cellular telephone to a cable network. The interface coupled in this way enables transmission and reception of communication signals to and from a cellular telephone network over the cable network allowing communication of the cellular phone to a cellular network connected to the cable network, for instance. The telephone network interface is further configured to enable the interface to communicatively couple with the cellular telephone using packet-based communication, such as session interface protocol (SIP) packet based communication.
