FEEDFORWARD LINEAR POWER AMPLIFIER WITH NEGATIVE GROUP DELAY CIRCUIT |
摘要 |
Provided is a feedforward (FFW) linear power amplifier (LPA) with a negative group delay circuit (300). The FFW LPA satisfies a group delay match condition through the negative group delay circuit (300) to improve linearity and efficiency, and does not use a delay element to reduce the volume and production cost of the LPA itself. To satisfy the group delay match condition, the negative group delay circuit (300) having a resonance characteristic is installed in the FFW LPA, and delay elements can be removed from the FFW LPA. |
