QUADRATURE AMPLITUDE DETECTION Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: quadrature amplitude detector has two transistors 1, 2, RC load circuit (on resistor 3 and capacitor 4), six resistors 5, 6, 9, 11, 14, 15, two capacitors 7, 8, two stabistors 10, 12, one stabilizer diode 13, two blocking capacitors 16, 17, paraphase output 18 of quadrature amplitude detector. Device realizes thermal stabilization of transmission factor under quadrature mode of detection when voltage of power supply source changes and in case of its stability within temperature interval. EFFECT: expanded application field. 1 dwg
