WebThis PNP Bipolar transistor is designed for high gain, low noise general purpose amplifier applications. It is housed in a TO-92 package for medium power applications. 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.

WebA low-noise amplifier has been designed utilizing a Toshiba 2SK117 N channel J-FET' as the input device in a cascode' configuration.
