Abstract (en)

[origin: EP1246294A2] A frequency-dependent effective length has output connectors linked to input connectors on an amplifier circuit (21) that has a field effect transistor (2) and a low-loss filter circuit (3) with an input admittance (7). At its input the filter circuit connects to a source connection for the field effect transistor. At its output (4) an HF receiving signal (8) is decoupled and the low-loss filter circuit is charged with an effective resistance acting at its output.
