Grid leak Detector.
A grid leak detector is an electronic circuit that demodulates an amplitude modulated alternating current and amplifies the recovered modulating voltage. The circuit utilizes the non-linear cathode to control grid conduction characteristic and the amplification factor of a vacuum tube. Invented by Lee De Forest … See more Early applications of triode tubes (Audions) as detectors usually did not include a resistor in the grid circuit. First use of a resistance in the grid circuit of a vacuum tube detector circuit may have been by Sewall … See more The stage performs two functions: • Detection: The control grid and cathode operate as a diode. At small radio frequency signal (carrier) amplitudes, square-law detection takes … See more Tetrode and pentode tubes provide significantly higher grid input impedance than triodes, resulting in less loading of the circuit providing the signal to the detector. Tetrode … See more • The grid leak detector potentially offers greater economy than use of separate diode and amplifier tubes. • At small input signal levels, the circuit produces higher output amplitude than a simple diode detector. See more The control grid and cathode are operated as a diode while at the same time the control grid voltage exerts its usual influence on the … See more The capacitance of the grid condenser is chosen to be around ten times the grid input capacitance and is typically 100 to 300 picofarads (pF), with the smaller value for screen grid and pentode tubes. The resistance and electrical connection of the grid leak … See more One potential disadvantage of the grid leak detector, primarily in non-regenerative circuits, is that of the load it can present to the preceding circuit. The radio frequency input impedance of the grid leak detector is dominated by the tube's grid input impedance, which … See more WebAug 29, 2014 · Grid leak resistors used on a grounded-cathode-grid-leak-bias setup carry dc current albeit very little.
