Abstract: Systems and method for improving design and/or operation of a radio frequency system are provided. One embodiment provides a radio frequency system, which includes a first look-up table that describes a static reference value, association between a maximum output power and a first specification level, and association between a first back off value and a second specification level, in which the first back off value is defined in relation to the static reference value and used to determine a first reduced output power; and a second look-up table that describes association between the maximum output power and a first set of operational parameters and association between the first reduced output power and a second set of operational parameters. The radio frequency system wirelessly transmits the analog electrical signal in compliance with an instructed specification level instruction by determining a desired output power based on the instructed specification level using the first look-up table and implementing operational parameters determined based on the desired output power using the second look-up table.

Abstract: A testing device determines an Effective Isotropic Radiated Power (EIRP) of a wanted signal at a beam-peak direction and a maximum Total Radiated Power (TRP) of the wanted signal. The testing device then determines a power difference (ΔP) between the EIRP of the wanted signal at the beam-peak direction and the maximum TRP of the wanted signal. The testing device determines EIRP of a spectral emission mask (SEM) at each measurement bandwidth step at the beam-peak direction. The testing device then determines TRP at each measurement bandwidth step by determining a difference between the EIRP of the SEM at that measurement bandwidth step and the power difference (ΔP). The testing device compares the TRP at each measurement bandwidth step to a SEM specification, and reports whether the SEM specification has been met.

Abstract: Methods and devices for reducing the power consumption and increasing the efficiency of an LTE transmitter of an electronic device are provided. By way of example, a method includes calculating location data related to a region in which the electronic device may operate via the electronic device, determining via the electronic device a region in which the electronic device is currently operating within based on the location data, and adjusting an output transmitting power of the electronic device based at least in part on the region and one or more frequency operating parameters utilized by the electronic device.
