Zusammenfassung:PROBLEM TO BE SOLVED: To provide a downsized low pass filter with excellent performance, and a high frequency switch employing the same. SOLUTION: A low pass filter 1 comprises a series resonance circuit (comprising L3 and C4) and a parallel resonance circuit (comprising L1 and C1) which are connected in cascade, grounded capacitors C2, C3 are connected across the parallel resonance circuit, and a transmission line L2 for phase adjustment is interposed between the series resonance circuit and the parallel resonance circuit. The high frequency switch 20 employs the low pass filter 1. COPYRIGHT: (C)2005,JPO&NCIPI
