RF7321

3V LTE Band 11, 21 Linear PA Module

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.
