BALANCED MIXER

An experimental study of a balanced mixer based on 2A116A-1 diodes was carried out.Conversion losses were measured in the input frequency range 2450 ± 45 MHz during downconversion to an intermediate 2125 MHz. Conversion loss does not exceed 20 dB anarrow band 2440±10 The amplitude characteristic taken, from which itcan be seen that it is linear for signals up 0 dBm (1 mW). dependence conversionlosses local oscillator power studied.
