| 20080311872 | Broadcast Signal Receiving Apparatus | 12-18-2008 |
| 20090033434 | OSCILLATION CIRCUIT - A first switch (SW | 02-05-2009 |
| 20090085672 | FREQUENCY SYNTHESIZER - By performing rough adjustment of a local oscillation frequency by a first lock loop using an up/down counter ( | 04-02-2009 |
| 20090085687 | MODULATING CIRCUIT - There are included a first quadrature modulation part ( | 04-02-2009 |
| 20090102546 | COMPOSITE BAND-PASS FILTER AND METHOD OF FILTERING QUADRATURE SIGNALS - A composite band-pass filter receives a quadrature input signal and passes an intermediate frequency signal while attenuating all other signals including an undesired image signal. The composite band-pass filter is comprised of a continuous time polyphase filter and a discrete time polyphase filter and can amplify signals. The amplification is distributed through out the composite band-pass filter and the amount of amplification may be selected by control signals. The composite band-pass filter has improved dynamic range and noise characteristics, selectable amplification and replaces an external crystal filter. | 04-23-2009 |
