Abstract: A radio frequency device includes antennas, transmitters, power detectors, a memory storing instructions and an antenna gain lookup table, and processors. The processors execute instructions that include instructing the transmitters to send transmission signals through the antennas to form a first beamformed signal having a first beam direction and a first frequency using multiple input powers. The instructions include determining radio frequency integrated circuit (RFIC) gains associated with the transmitters based on the transmission signals using the power detectors. Moreover, the instructions include determining the antenna gains for the antennas based on the first beam direction and the first frequency of the first beamformed signal, and the antenna gain lookup table. The instructions also include determining total gains based on the RFIC gains and the antenna gains, and adjusting the input powers based on the total gains and a back off power signal.

Abstract: An electronic device has multiple transmitters to transmit multiple signals. The electronic device also has a receiver to receive a signal. Moreover, the electronic device has a memory to store instructions and a processor to execute the instructions. The instructions cause the processor to send a test transmission signal from a transmitter of the multiple of transmitters, receive the test transmission signal at the receiver, and determine a gain of the test transmission signal. In response to determining that the gain is within a threshold range of an initial gain, the instructions cause the processor to send an indication that the receiver is operating as expected.
