Rout et al. [Linear Multilinear Algebra 2020, DOI: 10.1080/03081087.2020.1810201] presented cer- tainA-numerical radius inequalities for 22 operator matrices and further results onA-numerical radius of certain 22 operator matrices are obtained by Feki [Hacet. J. Math. Stat., 2020, DOI:10.15672/hujms.730574], very recently. The main goal of this article is to establish certainA-numerical radius equalities for operator matrices. Several new upper and lower bounds for the A-numerical radius of 2 2 operator matrices has been proved, where A be the 2 2 diagonal operator matrix whose diagonal entries are positive bounded operator A. Further, we prove some refinements of earlier A-numerical radius inequalities for operators
