Abstract :
This work describes the L-band low voltage (⩾1.6 V) power performance of AlGAs/GaAs heterojunction bipolar transistors (HBTs), their modeling and the design of a 2-W monolithic microwave integrated circuit (MMIC) for 3-V wireless mobile PCN applications (1800 MHz). The two-stage MMIC achieves 62% power-added efficiency (PAE) and 33 dB of linear gain, at a very small chip size of 1.2 mm2. To our knowledge this is the best combination of power performance data for wireless applications demonstrated so far for a MMIC. The chip size is about a factor of four smaller than comparable MMIC´s known before. The MMIC offers the potential both for low cost production due to small chip size, single voltage supply, and high performance at the same time
