Abstract
The object of the present invention is a low noise figure amplifier with a variable gain which comprises a cascode amplification stage comprising, serially mounted, a low-voltage MOSFET transistor installed as a common source followed by a bipolar transistor with high breakdown voltage installed as a common base. A resistor is placed between the bipolar transistor's collector and the grid of the cascode stage's MOSFET transistor, and the cascode stage is electrically powered through a choke.
