| 摘要 |
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. |
