VERY LOW INTERMEDIATE FREQUENCY IMAGE REJECTION RECEIVER WITH IMAGE INTERFERENCE DETECTION AND AVOIDANCE |
摘要 |
A method and apparatus for minimizing image interference using a very low intermediate frequency image rejection receiver is disclosed. Image interference detection and avoidance by frequency plan adjustment within the very low intermediate frequency receiver image rejection receiver minimizes rejection requirements for an image reject mixer. Image rejection can be measured by switching between in-phase and out-of-phase image reject mixer output ports. Rejection may also be measured by creating a tri-mode image reject mixer. A set of linear equations allows rejection to be measured without requiring control of input signals and additional mixers. |
