Efficient power amplifiers boost battery life

A new series of power amplifier modules promises the industry's best power-added efficiency for CDMA and GSM phones, allowing manufacturers to increase mobile phone battery life by as much as 15%.

Agilent Technologies has developed a new series of power amplifier (PA) modules for next-generation CDMA and GSM mobile handsets.

Agilent's new E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) PA modules provide the industry's best power-added efficiency (PAE) for CDMA and GSM phones, and allow manufacturers to increase mobile phone battery life by as much as 15%, a critical feature in today's multifunction phones.

Agilent's E-pHEMT process provides the industr
