RF BASICS and THEORY. "Very little is new in RF anymore. Almost everything that we see today is a variation on a very old and well understood theme"-- C. Marki. - Phased Array Antennas. - Understanding Noise Figure.
The circuit below is an old one, repeated many times. It was inspired by Fig 2.101 in EMRFD, the AA3X amplifier, but there are well documented examples online.
