General Description

The RF7234 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3V, 50 TD-SCDMA mobile cellular equipment and spread-spectrum systems.

This PA is developed for TD-SCDMA 1880MHz to 1920MHz and 2010MHz to 2025MHz frequency band, plus W-CDMA Band 1.

The RF7234 has two digital control pins to select one of three power modes to optimize performance and current drain at lower power levels.

Overview

RF7234 3V TD-SCDMA/W-CDMA LINEAR PA MODULE BAND 1 AND 1880MHz TO 2025MHz Package Style: Module, 10-Pin, 3mmx3mmx1.
