上传一个常用的射频PA功放资料，给大家参考
The RF7321 is a high-power, high-efficiency linear power amplifier
designed for use as final amplification stage in a 3V, 50 ohm LTE mobile
cellular equipment. This PA is developed for the E-UTRAN\LTE Bands 11
and 21 for which operates in the 1427.9MHz to 1462.9MHz frequency
band. The PA is specifically developed for 5MHz to 20MHz channel band-
widths used for the Band 11 or 21 operation on the LTE network. The
RF7321 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 RF7321 is fully
LTE compliant and is assembled in a 10-pin, 3mm x 3mm module.
