ABSTRACT:
Certain embodiments of the invention provide a method and system for symmetrically loading a divider circuit for multiband receivers. The method may comprise coupling a second divider circuit to an I component output signal of a first divider circuit and coupling a dummy load to a Q component output signal of the first divider circuit. The dummy load may comprise a load that may be equivalent to the second divider circuit. At least an I component output signal may be generated from the second divider circuit. At least a Q component signal may be generated from the second divider circuit. At least an I component signal generated from the first divider circuit may be received by the second divider circuit. At least a Q component signal generated from the first divider circuit may be received by a dummy load.
