AI Technical Summary

Problems solved by technology

However, since the application described uses standard switches, it does not provide low loss and optimum impedance in high power mode and broadband in low power mode
Therefore, due to the use of standard switches, there may be disadvantages such as insufficient frequency bandwidth due to non-ideal system impedance, large losses, power / efficiency mode performance loss, etc.

Embodiment Construction

[0034] Power amplifiers are used in different electronic devices to amplify the power levels of different signals. The power amplifier generally uses semiconductor devices for amplification. Due to hardware limitations, power amplifiers cannot simultaneously operate at high power, high efficiency, and wideband with flat gain. Therefore, in this application, a power amplifier system operating at high power, high efficiency narrowband or wideband is provided according to system requirements.

[0035] exist Figure 1-4 shows an exemplary view of the power amplifier system of the present invention, the system comprising at least one high power amplifier (2); at least one connection line (4); at least one input block (1) connected from the input terminal (I) receiving at least one signal, the input block is connected to said high power amplifier (2) and connection line (4), sends the received signal to high power amplifier (2) or connection line (4), and amplifies and sends to th...

Abstract

In the present invention, a power amplifier system which operates at a narrow band with high power and high efficiency or at a wide band is provided. Said power amplifier system comprises at least onehigh power amplifier (2); at least one connection line (4); at least one input block (1) which receives at least one signal from an input (I), which is connected to said high power amplifier (2) andconnection line (4), which sends received signal to either high power amplifier (2) or connection line (4) and which amplifies the power of the signal sent to the connection line (4); and at least onehigh power asymmetric output switch (3), which is connected to said high power amplifier (2) and connection line (4) and which sends signals coming from said high power amplifier (2) and connection line (4) to an output (O).

Description

technical field [0001] The invention relates to a power amplifier for amplifying the power of different electrical signals. Background technique [0002] Power amplifiers are used to amplify the power of various electrical signals such as radio frequency signals. The power amplifiers are used in various fields such as radar, jammer, wireless communication and imaging. Therefore, power amplifiers are especially important in the defense industry. [0003] The first power amplifiers were developed around the 1920s and included vacuum tubes for amplification purposes. Although such vacuum tube power amplifiers are still in use, solid-state power amplifiers consisting of semiconductor devices are now gaining popularity due to their performance and size advantages. Improvements in semiconductor technology have increased the performance of solid-state power amplifiers. However, current power amplifiers still lack performance, especially in wideband operation with high performan...
