| 20090115512 | DISTRIBUTED DOHERTY AMPLIFIERS - Doherty and distributed amplifier (DA) designs are combined to achieve, wideband amplifiers with high efficiency dynamic range. A modified Doherty amplifier includes a wideband phase shifter providing first and second outputs, a main amplifier coupled to the first output, an auxiliary amplifier coupled to the second output, and a wideband combining network combining the outputs in phase. A multi-stage DA has a main output and a termination port, and a phase delay module and transforming network allowing power at the termination port to be combined in phase with power at the main output. In one combination, one or more stages of the DA may comprise a Doherty amplifier. In another combination, a modified series-type Doherty amplifying system is achieved by cascading main and auxiliary DAs. In any combination, Doherty topology may include a bias control module. | 05-07-2009 |
| 20100112961 | SINGLE OSCILLATOR TRANSCEIVER - A frequency plan is provided for particular use in a transceiver. Advantageously, a single oscillator may be used to generate desired frequency signals. One or more power splitters receive the signal and equally divide the signal into first and second signals having a frequency substantially equal to the original. Multipliers on each arm of the transceiver receive a signal and increase the frequency of the signal. In one exemplary embodiment, multiple signals having different frequencies may be transmitted over the same cable due in part to the generated frequency separation between the signals. In another exemplary embodiment, multiple signals may be transmitted over multiple cables. In another exemplary embodiment, the frequency plan may self correct a transmit signal based on a reference signal, such as the receive signal. Additionally, multiple signals over one or more cables may be transmitted at or below 3 GHz. | 05-06-2010 |
| 20100117766 | CAPACITIVELY LOADED SPURLINE FILTER - In an exemplary embodiment, a spurline filter comprises a capacitive element connected to a spur and either a through-line of the spurline filter or ground. In another embodiment, multiple capacitive elements are connected to the spur. In an exemplary embodiment, the capacitively loaded spurline filter provides a band rejection frequency response similar to the band rejection frequency response of a similar spurline filter that does not comprise at least one capacitive element but the capacitively loaded spurline filter has half the layout area or less. In an exemplary embodiment, the spurline filter comprises capacitive elements, where the capacitive elements are configured to reduce the resonant frequency of the filter. | 05-13-2010 |
