6 FAQs about [Solid state power amplifier pdf]

Can a solid-state amplifier be produced in series?

All other subsystems should be kept the same for wide range of frequencies (from tens of MHz up to 1.3 GHz) and powers (from tens of kilowatts up to megawatt range) and hence can be produced in series. Figure 1: The general architecture of Siemens' solid-state amplifier.

Are RF power amplifiers suitable for scientific accelerators?

System components test results are discussed. A comparison of the state-of-the-art vacuum tube and solid-state technologies of RF power amplifiers for scientific accelerators is given. high frequency solid-state transistors lead to the expansion of solid-state technology on the RF amplifiers market.

Why is a single-ended power amplifier difficult to realize?

Single-ended difficult to realize at very high output power due to very low impedance at the output (2 drains in parallel). No Balun needed. Large number of transistors have to be stacked to reach high power levels. One device per power amplifier module. Redundancy. Failure affects minimally the whole amplifier.

What are high frequency solid-state transistors?

high frequency solid-state transistors lead to the expansion of solid-state technology on the RF amplifiers market. Developing Si, SiC, GaN, GaAs LDMOS, FET transistors allow building not only the drivers for vacuum tubes, but to substitute the entire RF systems .
