AI Technical Summary
Existing microwave tunable filters suffer from problems such as a wide variety of materials, high insertion loss, large size and weight, and high cost in terms of spectrum resource utilization. Furthermore, the use of circulators leads to non-interchangeability between transmit and receive signals and deterioration of echo performance.
By employing a compensation dielectric rod, tuning dielectric rods and compensation dielectric rods are placed in the high-end and low-end resonant cavities, thereby achieving frequency and coupling adjustment of the high-end and low-end filters, eliminating mutual interference at the common port, and avoiding the use of a circulator.
It realizes an adjustable duplexer with arbitrary transmit and receive intervals, with simple structure, good performance, reduced material types and costs, while maintaining the same echo suppression and out-of-band suppression performance.
