  Inspired by the discrete-variable pairwise entanglement, in this work, we in
theory analyze the continuous-variable pairwise entanglement between microwave
modes based on a hybrid optoelectromechanical system, where the multi-pair
microwave superconducting circuits simutaneously interact with each other via a
mechanical resonator, which forms a Fabry-P\'erot cavity along with a standing
mirror. With experimentally reachable parameter settings, wanted entanglement
can be acheived when the pair number up to 10, and more is also available,
which has the potential to be useful in quantum technologies where the demand
for scalability and intergration is continuously increasing.
