| 20090036068 | WIRELESS SYSTEM HAVING HIGH SPECTRAL PURITY - A wireless system having high spectral purity output signals. The wireless system has a transmitter circuit for transmitting an output signal and a power amplifier for amplifying the output signal for wireless transmission via an antenna. Positioned in-line with the output signal between the transmitter circuit and the power amplifier is a harmonic trap configured for inhibiting harmonics within a predetermined frequency range generated by the power amplifier from leaking into the transmitter circuit. The harmonic trap can be implemented as a discrete device, or integrated within the transmitter circuit or integrated within the power amplifier. By inhibiting the harmonics from leaking into the transmitter circuit, degraded performance of the transmitter circuit is prevented. | 02-05-2009 |
| 20090021321 | HYBRID LINEAR AND POLAR MODULATION APPARATUS - The invention is directed at a hybrid modulation apparatus which combines a polar modulation circuit and a linear modulation circuit. The hybrid apparatus allows a communications device to function as a polar or a linear modulation circuit with less components as the output of the linear modulation circuit is an input of the polar modulation circuit. | 01-22-2009 |
