Product Description  
Low Quiescent Current in Low  
Power Mode: 17mA  
The RF7234 is a high-power, high-efficiency, linear power amplifier  
designed for use as the final RF amplifier in 3V, 50TD-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. The part also has an integrated directional  
coupler which eliminates the need for an external discrete coupler at the  
output. The RF7234 is fully TD-SCDMA/W-CDMA/HSDPA-compliant and is  
assembled in a 10-pin, 3mmx3mm module.
