Radio transmission power amplifier output stage quadrimode hyperfrequency filter has resonant cavity with input/output waveguides irises coupled with irises/input/output faces parallel placed

摘要

The quadrimode hyperfrequency filter has a quadrimode resonant cavity of rectangular shape (16) with an input waveguide (10) and an output guide (12). Coupling to the resonant cavity is via two irises (15,17). The cavity faces and the irises are parallel to each other.
