Resource Overview

Synthesis of cross-coupled filters with source-load coupling. The F_P_E program calculates coupling coefficients F, P, and E based on transmission zeros and return loss specifications. The Cal_M module derives the coupling matrix from these computed coefficients. This program is primarily recommended for microwave filter design professionals. Others with related interests are welcome to explore the implementation.

Detailed Documentation

This synthesis program addresses cross-coupled filters incorporating source-load coupling interactions. The core algorithm utilizes an F_P_E computation module that processes specified transmission zeros and return loss parameters to generate three fundamental coupling coefficients: F, P, and E. These coefficients serve as inputs for the Cal_M matrix calculation module, which systematically constructs the complete coupling matrix representation. The implementation employs analytical synthesis techniques to ensure accurate filter response characteristics. Microwave filter specialists are encouraged to download this program for practical application and deeper methodological understanding. Interested researchers and engineers may also examine the code architecture to explore advanced coupling matrix synthesis methodologies.
