  • Voltage controlled high-frequency attenuator
    Patent number: 4839611
    Abstract: A continuously variable, passive attenuator including a signal path between an attenuator input node and an attenuator output node, the signal path including a passive resistive element connected between the input and output nodes, and a semiconductor element having a first terminal connected to the resistive element, a second terminal connected to a reference voltage, and a third terminal connected to a control signal node, the resistance of the semiconductor element between the first and second terminals being continuously variable as a function of the value of a control signal provided to the third terminal, the capacitance of the semiconductor element always being lessw than 4 pf.
