**Summary:**This paper realizes the reproducing kernel Hilbert spaces with orthonormal bases of the form $\{ (a_{{}_{n,0}} +a_{{}_{n,1}}z +\cdots + a_{{}_{n,J}} z^{J}) z^n : n \geq 0 \}$ in a matrix valued kernel setting. The question of when multiplication by $\phi$, denoted $M_\phi$, is a bounded operator is investigated and it is shown that $M_\phi$ can be viewed as the compression of a matrix valued Toeplitz type operator.
