    In the VHF range, high-quality narrow-band filters with reasonable physical dimensions are extremely difficult to realize. Excessive pass-band insertion loss accompanies filters employing lumped constant elements, and unreasonable size is a natural consequence of coaxial-resonator filters. Harmonic crystal filters are inadequate because of the unpredictable amount of spurious modes above the harmo... View full abstract»

    The performance of an inductor is often significantly compromised by the combined effects of series resistance and distributed capacitance. For a given inductance value and coil configuration, it is always possible to vary the absolute size and/or turns count so as to reduce one residual parameter at the expense of an increase in the other. The ratio M = L/RC2is unaffected by these tran... View full abstract»
