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 ...

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 ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...
