Abstract:
Aspects of this disclosure relate to active antenna calibration. In some embodiments, a local oscillator signal can be injected into the receive path for misalignment measurement and calibration of the receive path, a transmit signal from a transmit path can be coupled to a receive path, and the transmit path can be calibrated relative to the receive path.
Abstract:
Provided herein are apparatus and methods for using tuning information to adaptively and dynamically modify the parameters of an RF signal chain. The tuning information from an oscillator core, having multiple oscillators, adaptively tunes parameters of system components within a signal chain. In this way the system components are tuned to operate within a band tailored to the signal and to the oscillator core. In addition, RF impedances can be matched and power added efficiency can be enhanced in an area efficient monolithic integrated circuit.
