Abstract
A single-chipdual-band power amplifiermonolithic microwave integrated circuit (MMIC) operatingat 3.5V single supply has been developed for both WLAN2.4GHz and 5.2GHz with IEEE 802.11b/g/a standards applications. The MMIC utilizes the process of WINs Corp.with an InGaP/GaAs HBT process. The dual-band poweramplifierconstructed based on the design of adaptive RF bias chokecircuits and proper output matching networks.The proposed WLAN PA chip provides lowcurrentconsumption and high poweradded efficiency. The WLAN-PA is implemented as a two-stage MMIC with activebiasand input pre-matching and inter-stage matching networksintegrated. In addition, the PAis a broadband poweramplifier with above 20dBflat gain betweenthe frequencybands of 2.2GHz to 5.5GHz.
