A 45-2500-MHz Push-Pull Driver PA With Cross Coupled and Negative Feedback Technique

Derivative superposition technique (DST) is a common linearization technology for designing driver power amplifier (DPA). However, the performance of DST is sensitive to frequency variation. This letter presents a method to improve the 1-dB bandwidth of the DST. The negative feedback resistance (NFR...
