THREE_COIL_CRYSTAL_RECEIVER

Published:2009/7/12 23:44:00 Author:May | From:SeekIC

This circuit uses three inductors to increase the receiver's selectivity and sensitivity. Components L2 and C1 are used in an antenna impedance-matching circuit, while L1 and C2 operate in a series-tuned low-output impedance circuit that matches the impedance of the diode detector. A 1-to 2-mH inductor (L3), as in the previous circuit, offers dc continuity to the detector circuit.
