An extended band, multiple channel multiplexes 10 well-suited for use with satellite communications systems. The multiplexes utilizes a low attenuation, contiguous diplexer 18 containing contiguous diplexer filters 18a to combine two sections 11a, 11b of the multiplexes respectively containing contiguous channel filters 14a, 14b. The multiplexes comprises low attenuation, contiguous diplexer filters 18a tuned in tandem with channel filters 14a, 14b to provide contiguous multiplexing. This approach takes advantage of the constructive interaction between these filters to realize an equivalent contiguous multiplexes. This enables realization of a wide band contiguous multiplexes, which heretofore was impossible to tune. The contiguous diplexer eliminates spurious modes of the channel and diplexer filters, spurious waveguide modes, and out of band interaction between the two portions of the multiplexes. Therefore, tuning of the multiplexes is possible.
