  • Absorbent amplitude filter
    Patent number: 6087906
    Abstract: An absorbent amplitude filter for HF signals employs a reflective filter and an absorption circuit comprising a load resistor. The absorption circuit inventively comprises another .lambda./4 line upstream of the filter, which comprises, at the input side, a series connection consisting of another diode and the load resistor. This series connection is connected with the reference potential, whereby an HF block is connected in parallel to the load resistor.
