摘要: This letter describes a monolithic 3.5-to-6.5 GHz stacked power amplifier (PA) in 2 μm /0.5 μm GaAs HBT-HEMT process. The proposed PA is designed using both HBT and HEMT. Based on a common-emitter (CE) configuration of HBT with a stacked common-gate (CG) configuration of HEMT, a better power performance of 3 dB improvement can be achieved as compared with the conventional CE or common-source amplifier due to high output stacking impedance. By using the proposed method, the stacked PA demonstrates a maximum output power of 29.4 dBm, a compact chip size of 1.5 × 1 mm 2 , and a maximum power added efficiency (PAE) of 38%. The output power of the proposed PA is higher than 26.5 dBm between 3.5 and 6.5 GHz. 其他題名: LMWC 出版者: New York: IEEE 出版日期: 2012-09-01 出處: IEEE microwave and wireless components letters, 2012-09, Vol.22 (9), p.474-476 資源來源: IEEE Electronic Library (IEL) 版權: Copyright The Institute of Electrical and Electronics Engineers, Inc.
