A new true single supply power amplifier solution for dual and tri-band handsets
News & Analysis  
5/1/2002   Post a comment
Until recently, the depletion-mode GaAs antenna drivers used in most cell phones required a negative rail generator. This paper, reprinted from Microwave Engineering in the UK, describes the implementation of a three-stage dual-band single supply RF power amplifier for cellular handsets. With output matching, this device can be easily used in tri-band applications (GSM900/DCS1800/PCS1900). The IC is fabricated using 1m pHEMT enhancement mode technology developed specifically for single 3.6-V sup
