摘要:
The paper describes a diode noise generator designed as a standard source for measuring the noise factor of i.f. amplifiers in common use with centimetre-wave receivers.The output cable is fitted with an adaptor which plugs into the crystal holder of standard mixers and provides a convenient method of signal injection.The method of measurement requires no knowledge of the bandwidth, gain, or detector law of the amplifier under test.
