Abstract: Disclosed herein are signal amplifiers that include a plurality of switchable amplifier architectures so that particular gain modes can use dedicated amplifier architectures to provide desired characteristics for those gain modes, such as low noise figure or high linearity. The disclosed signal amplifier architectures provide tailored impedances using a degeneration block or matrix without using switches in the degeneration switching block. The disclosed signal amplifier architectures provide a plurality of gain modes where different gain modes use different paths through the amplifier architecture. Switches that are used to select the path through the amplifier architecture also provide targeted impedances in a degeneration block or matrix. The switches that select the gain path are provided in the amplifier architecture and are thus not needed or used in the degeneration block, thereby reducing the size of the package for the amplifier architecture.

Abstract: A technology is described for adjusting repeater gain based on user equipment need. A downlink path of the repeater can be deactivated. A deactivated throughput value can be received from the UE for data received at the UE in a selected time period. The downlink amplification path of the repeater can be activated. An activated throughput value for data received at the UE in the selected time period can be received from the UE. A difference can be determined between the deactivated throughput value and the activated throughput value. A repeater gain value can be reduced or bypassed when the deactivated throughput value is greater than the activated throughput value by a selected threshold value.

Abstract: This disclosure relates to variable-gain amplifiers that include degeneration circuits configured to adapt to a gain mode that is currently being implemented. For example, a variable-gain amplifier can operate in a plurality of gain modes to amplify a signal with different levels of amplification. The variable-gain amplifier can include a gain circuit configured to amplify a signal and a degeneration circuit coupled to the gain circuit. The degeneration circuit can include an inductor and a switching-capacitive arm coupled in parallel to the inductor. The degeneration circuit can operate based on a current gain mode to change an inductance for the variable-gain amplifier.

Abstract: In one example in accordance with the present disclosure, an antenna system is described. The antenna system includes an array of antennas. Each antenna emits electromagnetic waves and is presented with a load that is different from other antennas in the array. The antenna system also includes a control system. The control system includes a single transmitter to sequentially drive antenna sets, a switching device to select, for each activation period in an activation sequence, an antenna set to be driven, and a controller. The controller determines an actual power output of each antenna and generates an adjusted control signal for the single transmitter such that the output of each antenna is controlled to match a target power for that antenna, regardless of a load for the antenna.

Abstract: Envelope trackers providing compensation for power amplifier output load variation are provided herein. In certain configurations, a radio frequency (RF) system includes a power amplifier that amplifies an RF signal, an output detector coupled to an output of the power amplifier and that generates an output detection signal, an input detector coupled to an input of the power amplifier and that generates an input detection signal, and an envelope tracker that generates a power amplifier supply voltage for the power amplifier based on an envelope of the RF signal. The envelope tracker compensates the power amplifier for output load variation based on the output detection signal and the input detection signal.

Abstract: A gain controller sets a gain code indicating an optimum gain, a cutoff frequency code indicating a cutoff frequency, and a number of bits code indicating a number of bits. An AEQ/VGA gain controller sets a frequency characteristic code indicating a frequency characteristic, a gain code indicating a gain after correction, and a number of bits code indicating a number of bits. An AEQ/VGA amplifies a baseband received signal on the basis of a gain code and corrects a frequency characteristic of the baseband received signal on the basis of a frequency characteristic code. An HPF cuts off a band below a cutoff frequency of an output signal from the AEQ/VGA on the basis of a cutoff frequency code. An ADC quantizes an output signal from the HPF using a number of bits based on a number of bits code and generates a digital received signal.

Abstract: A receiver front end capable of receiving and processing intraband non-contiguous carrier aggregate (CA) signals using multiple low noise amplifiers (LNAs) is disclosed herein. A cascode having a “common source” input stage and a “common gate” output stage can be turned on or off using the gate of the output stage. A first switch is provided that allows a connection to be either established or broken between the source terminal of the input stage of each cascode. Further switches used for switching degeneration inductors, gate/sources caps and gate to ground caps for each legs can be used to further improve the matching performance of the invention.

Abstract: A Variable Gain Amplifier (VGA) amplifies an input signal according to a gain, to produce an amplified signal. A detector module detects a power indicative of a power of the amplified signal. A comparator module compares the detected power to a high threshold, a low threshold and a target threshold intermediate the high and low thresholds. A controller module changes the gain of the VGA so as to drive the detected power in a direction toward the middle threshold when the comparator module indicates the detected power is not between the high and low thresholds.
