Description

The TQM7138 is a 3V, 2 stage SiGe HBT Power Amplifier Module designed for use in mobile phones. Its extremely small 4x4mm package makes it ideal for today's extremely small data enabled phones. Its RF performance meets the requirements for products designed to IS-95/98 standards. The TQM7138 provides the capability to be operated in one, two, or continuous quiescent current modes. In digital quiescent current mode operation, the TQM7138 is controlled from the base-band processor using a CMOS compatible ICQ voltage control voltage. Overall current consumption of the device is minimized by selecting the lowest ICQ state available for each power output level. RF input and output matching is included within the module; therefore, minimal external circuitry is required.

The TQM7138 gives excellent RF performance with low current consumption resulting in longer talk times in portable applications. The small 4mm square surface mount package is ideal for new generation small and light phones.
