In-line pseudoelliptic band-reject filters with nonresonating nodes (NRNs) and/or phase shifts are introduced. It is shown that general band-reject filters with arbitrarily placed reflection zeros (RZs) can be designed by both classes. A more general low-pass network, which contains both NRNs and phase shifts, is introduced. Prior to implementation, the network, which includes phase shifts, is optimized to take into account dispersion effects and better fit the specifications. Example filters… CONTINUE READING
