Scientists have developed a chip smaller than a strawberry seed to boost space communications. The tiny signal amplifier is ...

Smaller than a strawberry seed, this tiny signal amplifier was produced by the European Space Agency to fill a missing link ...

they can be represented as part of small signal model as shown below Noise Analysis of Common Source Amplifier with resistive load: The small signal equivalent of above circuit including noise sources ...

Both these devices should only be used when necessary. In many cases a good aerial installation with good quality cables can be enough to receive good reception. A signal amplifier should only ...
