- Missing chicken pile of feathersMay 20, 2007 · Linear Amp Tuned Input The biggest single improvement that can be made to the simple GG RF amplifier is the addition of a tuned input. The tuned input improves linearity while also reducing the drive requirements. Many users claim 500W output from amplifiers based on this valve. Taking that as a design objective, and limiting the DC anode - cathode voltage to about 2.2kV, an initial load line can be calculated using Calculate initial load line of valve RF amplifier. Taking a guess that the anode can be driven down to 200V, and it is a guess as will be ...
- A high efficiency amplifier would have many advantages: Smaller, lighter, possibly cheaper, lower energy consumption, longer component lifespan and reliability, lower or no fan noise, among others. And if the amplifier uses a switching scheme instead of conventional linear amplification,... RF amplifiers are electronic devices that accept a varying input signal and produce an output signal that varies in the same way as the input, but that has larger amplitude. RF amplifiers generate a completely new output signal based on the input. Depending on load of the output circuit, one or more ...
