RF Micro Devices Intros RF3140 Power Amplifier

RF Micro Devices Inc. (Greensboro, NC) announced the availability of the RF3140, a high-efficiency, quad-band, power amplifier module with integrated power control circuitry. The RF3140 represents the second generation of RFMD's PowerStar™ family of power amplifier modules, all of which feature power control functionality based on collector control.

The RF3140 is designed for use as the final RF amplifier in single- and multi-band GSM 850, EGSM, DCS and PCS hand-held digital cellular equipment and other applications in the 824MHz to 849MHz, 880MHz to 915MHz, 1,710MHz to 1,785MHz and 1,850MHz to 1,910MHz bands. The RF3140 includes a fully integrated, high-voltage, silicon CMOS power control loop that meets all spectrum and burst-timing requirements, with 50-ohm input and output terminals. To simplify engineering effort and shorten development cycle time, the RF3140 also includes software tools that allow the engineer to instantly calculate ramp profiles.

The module is available in a small 10mm x 10mm, lead-less chip carrier, minimizing the required board space. Samples and fully assembled evaluation boards are available now.
