Abstract
Broadband single-ended and push-pull monolithic microwave integrated circuit (MMIC) amplifiers are presented which achieve high gain per milliampere and demonstrate excellent cascadability. The single-ended 6 to 18 GHz amplifier shows 10+or-1 dB gain for a 25-mA current. The push-pull amplifier shows 10 dB gain for a 50-mA current with higher output power of 12 dBm at 1 dB gain compression; and has the added features of gain equalization and gain control. A module designed with four push-pull chips shows excellent gain flatness of 34+or-1 dB. Both of these MMICs are compact (36*48 and 48*48 mils) and demonstrate high overall yield (above 80%) due to the absence of via holes and other yield-limiting process steps.<>Keywords
