Product Description
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-UTRANLTE 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 bandwidths 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.
