Abstract

PURPOSE:To get rid of the obstacles at the time of reception due to the local oscillation output, by using other transistor for the transistor for converting frequency in the frequency converting circuit of the receiver, and setting off the local oscillation output which is leaking in the collector of the local oscillation circuit.
