摘要
An active circuit comprising a component coupled between an input terminal and an output terminal, the component requiring power to operate, and a bypass path which causes a signal to propagate from the input terminal to the output terminal via the component when the component is operating under power and which causes the signal to bypass the component, when the circuit loses power, and propagate from the input terminal to the output terminal via a section of transmission line, the bypass path comprising a bypass circuit having at least two FETs, the two FETs providing high and low impedances, the high impedance being provided when the component is operating, thereby causing the signal to propagate from the input terminal to the output terminal via the component and the low impedance being provided when the circuit loses power, thereby causing the signal to propagate from the input terminal via the section of transmission line to the output terminal. The active circuit according to the present invention further comprises at least four PIN diodes for preventing an output signal feedback at the input terminal.
