摘要：
We demonstrate a new structure of the single-input single-chain power amplifier for cellular (850 MHz)/PCS (1750 MHz) dual-band operation. The single-input structure seems adequate for the reconfigurable nuiltiband transinitter and the single-chain structure can achieve a small chip and module size, thus reducing manufacturing costs. This two-stage amplifier has a maximum output power of 30 dBm (29 dBm). a power-added efficiency, (PAE) of 42% (37%), and an adjacent channel power ratio (ACPR) of -51 dBc (-48 dBc) at the output power of 28 dBm (28 dBm) under 3.4-V operation voltage for cellular (PCS) band.
