WebAn efficient way of doing this is to use a noise filtering technique. An inductor L3 and capacitor C5 forms a 2nd order low-pass filter which prevents noise at even harmonics from being injected into the feedback path of the oscillator. The noise filter leaves low-frequency noise from the tail current source unaffected. pagamenti bolli regione lombardiaWebNoise Figure as low as 0.38 dB IP3 up to +44.8 dBm All Low Noise Amplifiers Browse Our Full Low Noise Amplifier Selection!
