The 800-mW NESG250134 and 1W NESG260234 medium-power SiGe (silicon-germanium) HBT (heterojunction-bipolar-transistor) amplifiers suit use in two-way radio applications, such as FRS (Family Radio ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

[Paulo] just tipped us about an Excel based high frequency transistor amplifier calculator he made. We’re guessing that some of our readers already are familiar with these class A amplifiers, commonly ...

Liam Devlin and Andy Dearn describe the design of a 25W X-band gallium nitride (GaN) power amplifier. Gallium nitride (GaN) technology is very well suited to the realisation of solid-state microwave ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a 3-MO load resistor and ...
