Product Description

The RF7252 is a high-power, high-efficiency linear power amplifier

designed for use as final amplification stage in 3V, 50 UMTS/CDMA

mobile cellular equipment. This PA is developed for UMTS Band 2 and

CDMA PCS band which operates in the 1850MHz to 1910MHz frequency

range. The RF7252 has two digital control pins to select one of three

power bias states 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

RF7252 meets spectral linearity requirements for CDMA, HSDPA, and

HSUPA data transmission. The RF7252 part is assembled in a 10-pin,

3mm x 3mm module.
