Title:
PHASE ADJUSTMENT CIRCUIT AND ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/082866
Kind Code:
A1
Abstract:
A phase adjustment circuit comprises: a local frequency band phase shifter that adjusts the phase of a signal in a local signal frequency band, and outputs the adjusted signal; a frequency conversion mixer into which are inputted the adjusted signal along with another signal different from the adjusted signal, and which mixes the adjusted signal and the other signal; and a buffer amplifier that is provided in between the local frequency band phase shifter and the frequency conversion mixer, and that can amplify the input power inputted into the frequency conversion mixer up to a range of input power in which the input/output characteristics of the power of the frequency conversion mixer are located outside of a linear region.
