Product Description
The RF7321 is a high-power,www.DataSheet.net/ 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.

Pin-Out Description
Description
Supply voltage for the bias circuitry.
RF input internally matched to 50 and DC blocked.
Digital control input for power mode selection.
Digital control input for power mode selection.
Digital control input for PA enable and disable.
Coupler output.
This pin must be grounded.
Coupler input used for cascading couplers in series. Terminate this pin with a 50 resistor if not connected to
another coupler.
RF output internally matched to 50 and DC blocked.
Supply voltage for the first and second stage amplifiers which can be connected to the battery supply or output
of the DC-DC converter.
Ground connection - this package backside should be soldered to a topside ground pad connecting to the PCB
ground plane with multiple ground vias. The pad should have a low thermal resistance and low electrical imped-
ance to the ground plane.
