New GPRS Amp from Motorola

Motorola is introducing a quad-band GSM/GPRS single power supply Power Amp module, made by combining High Impedance Integrated Power Amplifier (HIIPA) packaging, and true enhancement-mode (E-mode) GaAs wafer process technologies.

The wide band matching advantage brought by the HIIPA technique provides a flexible PA solution that is able to adapt to GSM/GPRS application requirements. It is suitable for all four of the GSM frequency bands - 900, 1800, 1900 and 800.

"Because of its low off-state leakage current, this true enhancement-mode device eliminates the drain-supply switch required for depletion-mode pseudomorphic high electron mobility transistor (pHEMT) and metal semiconductor field effect transistor (MESFET) devices," said Karl Johnson, vice president and director of Motorola's Compound Semiconductor Technologies DigitalDNA(TM) Laboratories. "The E-mode GaAs technology helps to reduce the cost and size of the end product by eliminating both the negative voltage generator and the drain-supply switch within the handset power amplifier section, as well as eliminating additional passive components."'"
