A radio frequency passband filter comprising a network of half-wavelength planar resonators, wherein at least one of the half-wavelength planar resonators includes a resistor shunted to ground to flatten response in the passband, and wherein different ones of the half-wavelength planar resonators have resistors with different resistance values.
A radio frequency passband filter comprising:
- a network of half-wavelength planar resonators, wherein at least one of the half-wavelength planar resonators includes a resistor shunted to ground to flatten response in the passband;
- and
- resistive couplings between different resonators in the network of half-wavelength planar resonators.
A radio frequency passband filter comprising a network of half-wavelength planar resonators, wherein at least one of the half-wavelength planar resonators includes a resistor shunted to ground to flatten response in the passband, and wherein the resonators are formed from a printed metallization bonded to a substrate using a liquid crystal polymer.
