International Classification:

H04B 1/40
H04B 1/10

Abstract:

Certain aspects of the present disclosure generally relate to techniques and apparatus for operating a wireless receiver of the apparatus in a high linearity mode. An example method includes operating the apparatus in a first mode with transmission of a plurality of transmit signals. The method also includes attenuating a received signal via an attenuator while operating the apparatus in the first mode. The method further includes amplifying the attenuated signal with an amplifier while operating the apparatus in the first mode. For certain aspects, the method further involves operating the apparatus in a second mode, bypassing the attenuator while operating the apparatus in the second mode, and amplifying the received signal with the amplifier while operating the apparatus in the second mode.

International Classification:

H03F 3/19
H03F 1/56

Abstract:

An amplifier may include multiple stages, with the multiple stages arranged in a fan-out configuration. The fan-out configuration provides multiple amplified signals at multiple amplifier output nodes, which may be coupled to a shared set of downconverters. The shared downconverters may support processing of only a smaller bandwidth than the largest possible bandwidth of an input RF signal input to the amplifier. For example, the downconverters may support a bandwidth matching a smallest bandwidth of a supported RF signal. For example, when the amplifier is intended to support 5G mmWave RF signals and 5G sub-6 GHz RF signals, the downconverters may each individually support a bandwidth of carriers in the 5G sub-6 GHz RF signals but not individually support the entire bandwidth of a possible 5G mmWave RF signal.

Abstract:

This disclosure provides systems, methods, and devices for wireless communication that support reconfiguring degeneration components in a converged RF transceiver supporting carrier aggregation across sub-6 GHz frequency bands and mmWave frequency bands. In a first aspect, an apparatus includes an input port configured to receive a mixer input signal; a first mixer forming at least a portion of an HRM mixer and coupled to the input port; a first configurable degeneration component of a first processing path coupled between the input port and the first mixer; and a controller coupled to the first degeneration component, wherein the controller is configured to control a first aspect of a first degeneration component. Other aspects and features are also claimed and described.
