Abstract(in English) Single-band (SB) and multiband (MB) power amplifier modules (PAM) are demonstrated for WCDMA handsets applications. The PAMs feature bulk Si-CMOS and GaAs-HBT hybrid architecture for pursuing low cost while maintaining high efficiency and high- and low-power mode (HPM and LPM) function. In the PAMs, the CMOS die accommodates a driver stage for the HPM, two power stages for the LPM, and several RF switches in addition to their-related bias and switch control functions. A power stage and its related bias block for the HPM are integrated on the GaAs-based HBT die, and a band select switch used in the MB PAM is implemented using a GaAs-based HEMT process. Measurements under a condition of WCDMA modulation (3GPP, R99) and 3.4-V power supplies show that the SB PAM operating in 880-915MHz can deliver a 28.5dBm output power (Pout), a 44% power-added efficiency (PAE), and a -39dBc 5-MHz-offset adjacent channel leakage power ratio (ACLR) in the HPM. In the LPM, a PAE as high as 20% is obtained at 17dBm of Pout. The MB PAM operating in the bands of 824-915MHz and 1850-1980MHz also achieves high PAE of 35~40% in the HPM and 14~15% PAE in the LPM while keeping ACLR of less than -37dBc.
