Linear amplifiers are typically preferred for use with Citizen's Band (CB) radios despite their low efficiency. This is because the CB application prioritizes low-noise over power efficiency, something which a linear amplifier offers. Weak signals can limit the operation of your CB radio and an ...
SOLUTION: In this linear amplifier of two or more stages using grounded emitter transistors as amplifiers, a bias circuit for supplying the bias voltages for DC bias of the amplifier transistors of the respective stages is constituted by parallel connecting a first current mirror circuit of a high...
