AX508 GSM/GPRS Quad Band Power Amplifier

The AX508 device integrates a full quad band GSM/GPRS power amplifier function on a single Integrated Circuit (IC) using advanced 0.13 μm silicon CMOS process technology. Key benefits of the AX508 include improved performance, relative to its AX502 product, equating to a longer talk time. With the AX508, Axiom Microdevices also offers a smaller footprint by housing the PA in an ultra-low profile micro lead frame package measuring 5x3.5x0.9 millimeters (mm). Axiom Microdevices’ CMOS power amplifiers were developed using the company’s patented Distributed Active Transformer (DAT) technology, which has made it possible to use 0.13-micrometer silicon CMOS process technology to integrate all of the functions between transmitter output and transmit/receive switch. Leveraging DAT technology, Axiom Microdevices realizes power gain stages, small signal control circuitry and 50-ohm input and output matching circuitry on a single die, enables direct connection to the transceiver output and the transmit/receive switch input without the use of the external matching components, helping designers to achieve what was previously only viable with devices manufactured in proprietary gallium arsenide (GaAs) process technology and assembled in complex multi-chip module packaging.
