Simple design with a constant K-type high-frequency low-pass LC filter

  
Due to the amplifier frequency characteristics and impact of parasitic capacitance, to make hundreds of kilohertz to the active filter is very difficult.. On the other hand, si
Simple design with a constant K-type high-frequency low-pass LC filter - schematic

nce the circuit constituted by LO J low-pass filter, the volume of the coil inductance L and the circuit is relatively large, but the frequency in MHz or more can be done when the miniaturization of practical value o 0 filtering workers clamor basic form called a constant K-type filter, an intuition, circuit design and R is the same port filter. Under normal circumstances, pottery item parameter signal flooded due to the load resistance and anti varies, here takes a value equal to
