Abstract :
An injection phase-locked oscillator is used as an input microwave-limiting amplifier for a microwave discriminator (FM demodulator) used for noise measurement. This amplifier simultaneously increases sensitivity by 6 dB and reduces the threshold (minimum measurable FM) by at least 10 dB. The oscillator can be frequency-modulated to calibrate the measurement.
