Low pass filter design with improved stop‐band suppression and synthesis with transformer‐free ladders
Abstract A new method to design transformer‐free low pass (LP) ladder network with improved stop‐band suppression performance is introduced. The parametric representation of back‐end impedance of LP filter network is established with minimum impedance part and a Foster reactance part. The constructe...

| description | Abstract A new method to design transformer‐free low pass (LP) ladder network with improved stop‐band suppression performance is introduced. The parametric representation of back‐end impedance of LP filter network is established with minimum impedance part and a Foster reactance part. The constructed impedance function is optimized by using real frequency technique. It has been shown that the proposed method provides LP filters which have superior stop‐band suppression in comparison with classical transfer function‐based filters with same complexity. The synthesis of the LP filter is obtained with the proposed element extraction procedure and resulted with fully realizable network elements in ladder form. An LP filter design and application by employing the proposed technique is provided. The measurement results of the prototyped filter are presented. |
