Abstract :
Phase response characteristics of multiband filters, as well as diplexers, with different amplitude response characteristic approximations based on high-pass and low-pass filters are studied. An absolute diplexer phase reaches the maximum at the frequency when LPF and HPF amplitude response characteristics intersect. The phase maximum value depends on juncture bandwidth and channel isolation.
