摘要： In a filter arrangement comprising a frequency filter (F) that has a bad or non-ideal ground connection (GC1, 2, 3, 4, 5, 6, 7), the defects arising from bad ground are compensated by a capacitance (CC) coupled in parallel to the frequency filter. The value of the capacitance is chosen between 1 and 50 fF. The filter arrangement may be a receiving filter (RF) in a duplexer (DU).
