Abstract
The filter comprises a series branch formed by an inductance coil (L) in parallel with a resistor (R1) and a parallel branch formed by a capacitor (C) in series with a resistor (Rc). For frequencies such that Rc>>1/.omega.C and R1<<.omega.L, the ratio between the output and input powers of the filter has a predetermined maximum value strictly lower than 1 and independent of the load impedance.
