The objective of the circuit is to create a medium power amplifier based on the functionality of a HEXFET to produce a good quality of sound while providing 65W of power output. BC550 – an NPN general ...

The circuit was based on HEXFET technology to create a power amplifier that would produce an output power of 45 Watts. LF351 – a wide bandwidth single JFET operational amplifier with high slew rate, ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

If you need an amplifier, [Hans Rosenberg] has some advice. Don’t design your own; grab cheap and tiny RF amplifier modules and put them on a PCB that fits your needs. These are the grandchildren of ...
