Abstract: | The authors present a push-pull transformer-coupled amplifier for monolithic microwave applications, and discuss how its stability and layout have been improved with respect to conventional approaches by means of opposite-phase feedback and fully symmetrical layout. The circuit provides state-of-the-art performance (10-dB gain and 18-dBm saturated power in the 4-8-GHz band) with only 165-mW DC power consumption |
