Shunt stub design
WebA Summary of Shunt Stub Matching Theory. The design of the shunt tuning stub utilized in the previous part is now explained. Let the load impedance be Z L = 1 / Y L = R L + j X L. … WebIn microwave and radio-frequency engineering, a stub or resonant stub is a length of transmission line or waveguide that is connected at one end only. The free end of the stub …
