<p>Connection topology of input terminals (2), elements (4a, 4b, 4c, 4d) and a load (5) is made as a "7-segment display" applied to numerical display for a calculator or a digital clock and the like. That is, if the uppermost and lowermost segments among three horizontally extending segments in the 7-segment display are assigned to the input terminals (2) and the load (5) is assigned to one remaining horizontally extending segment, four remaining longitudinal segments correspond to the elements (4a, 4b, 4c, 4d). The elements (4a, 4b, 4c, 4d) are an inductor having inductance of 4.030nH, an inductor having inductance of 11.208nH, an inductor having inductance of 2.497nH, and a capacitor having capacitance of 2.233pF, respectively. This circuitry can reduce the total number of elements to 4 thereby realizing low loss property. In addition, as a resonance circuit is eliminated from constituent circuits and a scale of a ladder circuit is reduced, highly stable impedance matching is attained against impedance fluctuation of the load (5).</p> |
