Product Description
The RF3145 is a high power, high efficiency power amplifier module with integrated power control. This module is self-contained with 50 Ω input and output terminals. The device is manufactured on an advance Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final dual-mode GMSK/8PSK RF amplifier in GSM, DCS and PCS hand-held cellular equipment and other applications in the 824MHz to 849MHz, 880MHz to 915MHz, and in the 1710MHz to 1910MHz bands. Internal band select provides control to select the GSM850/GSM900 or DCS/PCS band. The device is packaged on ultra-small LCC, minimizing the required board space.
