HARMONIC SUPPRESSION FOR A MULTI-BAND TRANSMITTER |
| 摘要 |
<p>A multiple band transmitter (100) including first and second transmit amplifier paths (110, 120), where the first transmit amplifier path (110) conducts a first transmit signal at a first frequency band and the second transmit amplifier path (120) conducts a second transmit signal at a second frequency band. The second transmit amplifier path (120) includes an amplifier (103) that generates the second transmit signal along with a harmonic frequency within a passband of the first transmit amplifier path (120). The second transmit amplifier path (120) further includes a trap circuit (130, 230) that shunts the harmonic frequency away from the first transmit amplifier path (110).</p> |
