Disclosed is an antenna device, antenna system, and methods to create, and install or modify, an antenna profile for an antenna device so as to direct remotely the propagation of radio frequency signal from the antenna device to targeted radio frequency geographic coverage areas. Ports may be selected to activate spatial segments created by the configuration of the reflectors, joined about a cylindrical core, which may be quadrants when the reflectors are configured into a cross-like shape. The system provides aid in orienting an antenna, upon installation, to a pre-designated geographic heading. Optionally, the tilt of each quadrant of an antenna device may be determined so as to ensure proper radio frequency coverage.

The present disclosure relates to a radio frequency (RF) measurement system and a method for recording baseband and positioning data. The RF measurement system includes at least one RF measurement device. The RF measurement device includes at least one RF chain and at least one data processing circuit connected to a memory device. The RF measurement device is configured to receive a global navigation satellite system (GNSS) signal. The GNSS signal is indicative of a position and/or a bearing. The RF measurement device is configured to receive at least one analog RF signal different of the GNSS signal. The RF measurement device is configured to convert the at least one analog RF signal into at least one baseband signal. The at least one data processing circuit is configured to store baseband data associated with the baseband signal and positioning data associated with the GNSS signal within the memory device.

Examples described herein include methods, devices, and systems which may compensate input data for nonlinear power amplifier noise to generate compensated input data. In compensating the noise, during an uplink transmission time interval (TTI), a switch path is activated to provide amplified input data to a receiver stage including a recurrent neural network (RNN). The RNN may calculate an error representative of the noise based partly on the input signal to be transmitted and a feedback signal to generate filter coefficient data associated with the power amplifier noise. The feedback signal is provided, after processing through the receiver, to the RNN. During an uplink TTI, the amplified input data may also be transmitted as the RF wireless transmission via an RF antenna. During a downlink TTI, the switch path may be deactivated and the receiver stage may receive an additional RF wireless transmission to be processed in the receiver stage.

A semiconductor chip includes a first wireless communication circuit, a local oscillator (LO) buffer, and an auxiliary path. The first wireless communication circuit has a signal path, wherein the signal path has a mixer input port and a signal node distinct from the mixer input port. The auxiliary path is used to electrically connect the LO buffer to the signal node of the signal path. The LO buffer is reused for a loop-back test function through the auxiliary path.
