Abstract

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 multiband transmitter 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. © 2006 Wiley Periodicals, Inc.
