| 20110175789 | RF MODULE AND ANTENNA SYSTEMS - Architectures and implementations of a transceiver system for wireless communications are presented, the system including one or more antennas supporting a single frequency band or multiple frequency bands, a transmit circuit, a receive circuit, and an isolation circuit that is coupled to the one or more antennas and the transmit and receive circuits and provides adequate isolation between the transmit circuit and the receive circuit. | 07-21-2011 |
| 20110210787 | SWITCHLESS BAND SEPARATION FOR TRANSCEIVERS - A system includes a plurality of band pass filters to pass signals in separated frequency bands to or from an antenna. A matching network provides characteristic impedances. The system is designed such that the configuration of the matching network and BPFs provides high impedance to the band pass filters for those routing paths other than the band pass path as these routing paths do not transmit or receive the signals at this particular pass band. The system is further designed such that the configuration of the matching network and BPFs provides minimal insertion loss for the band pass path of for transmission and receipt of signals at this particular pass band, where each routing path has a corresponding pass band. The matching network is for coupling to an amplifier, when frequency separation is needed at the output of the amplifier to the BPFs. In one embodiment an impedance network tunes the impedance by using varying length transmission lines. | 09-01-2011 |
