RF_SIGNAL_STRENGTH_INDICATOR

Published:2009/7/16 4:06:00 Author:Jessie | From:SeekIC

This circuit is useful for test purposes because it produces an output that varies logarithmically with RE input level. A Motorola MC3356 IC is used for its received signal strength output (pin 14), the other functions remain unused. An attenuator is placed at the input of the circuit to increase usable range. For best results, the circuit should be enclosed in a metal shielded box.
