Title:
TEMPERATURE-COMPENSATION CIRCUIT AND PHASED ARRAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/087367
Kind Code:
A1
Abstract:
The present application provides a temperature-compensation circuit and a phased array device for reducing the influence of temperature changes on the gain in a signal processing path. The temperature-compensation circuit is applied to the signal processing path. The temperature-compensation circuit comprises a temperature detection circuit, a temperature conversion circuit, and a passive variable attenuator. The passive variable attenuator is used for being connected in the signal processing path in series; the temperature detection circuit is used for generating a temperature signal and a reference signal, and the temperature signal and the reference signal are outputted to the temperature conversion circuit, wherein the temperature signal changes monotonically with the temperature of the signal processing path; the temperature conversion circuit is used for generating a control signal according to the temperature signal and the reference signal; the passive variable attenuator is used for adjusting the attenuation of a signal processed by the signal processing path under the control of the control signal.
