WebDec 10, 2015 · RF Driver Amplifier. Driver: a driver RF amplifier’s primary role is to source and sink sufficient current at the operating frequency to drive a low-impedance load such as a 50- or 75-Ω coaxial cable. RF drivers can also be considered as RF power amplifiers, when their role is to provide a power boost (current and/or voltage) to drive a load ... WebThe operational amplifier is used to eliminate the (rightmost) diode's threshold voltage by inserting the diode within the feedback loop. ... Use this "transmitter" to provide RF for designing your crystal radio. When you can receive a strong signal, crank the transmitter output way down, then redesign your radio to bring it back up again ... durango roper boots
