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 ...

NEC is now offering a 2-W SiGe HBT transistor amplifier for two-way radio applications including FRS, GMRS, and SMR, as well as general UHF and ISM band applications. NEC is now offering a 2-W SiGe ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

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 ...
