L. Selmi et B. Ricco, DESIGN OF AN X-BAND TRANSFORMER-COUPLED AMPLIFIER WITH IMPROVED STABILITY AND LAYOUT, IEEE journal of solid-state circuits, 28(6), 1993, pp. 701-703
This paper presents a push-pull transformer-coupled amplifier for mono
lithic microwave applications, and discusses how its stability and lay
out have been improved with respect to conventional approaches by mean
s of opposite-phase feedback and fully symmetrical layout. The circuit
provides state-of-the-art performance (10-dB pin and 18-dBm saturated
power in the 4-8-GHz band) with only 165-mW dc power consumption.
