Product Description
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.
