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.
