Problems solved by technology

However, in the design of traditional high-efficiency power amplifiers, there have always been some design problems, mainly reflected in the difficulty of multi-frequency and multi-mode when compatible with high-efficiency indicators and mutual constraints
In order to ensure the high-efficiency and high-gain operation of the amplifier, the transistor must achieve a good and accurate compromise between the best efficiency and gain matching in the multi-frequency mode, but the realization of the multi-frequency power amplifier has always been the technical bottleneck
[0003] Common high-efficiency, high-gain multi-frequency power amplifier circuit solutions include multiple single-frequency point power amplifiers to form a load amplification system, and each power amplifier achieves the best circuit design at its own frequency point, but this type of amplifi

Abstract

The invention discloses a multi-mode eight-frequency high-efficiency high-gain power amplifier which comprises a multi-mode eight-frequency input matching network, a three-stack self-bias power amplification network and a multi-mode eight-frequency output matching network which are connected in sequence. The grid power supply bias network and the drain power supply bias network are respectively connected with the multimode eight-frequency input matching network and the multimode eight-frequency output matching network. The power amplifier has the beneficial effects that a three-stack transistor structure based on a self-bias structure is adopted, and a multimode LC matching network is combined, so that the power amplifier has multimode characteristics of high efficiency, high gain and highpower output capability at eight frequency points.

Description

technical field [0001] The invention relates to the field of a field effect transistor radio frequency power amplifier and an integrated circuit, in particular to a multi-mode, eight-frequency, high-efficiency and high-gain power amplifier for application to a radio frequency front-end transmitting module of a multi-frequency and multi-mode communication system. Background technique [0002] With the development of modern military and civilian communication technologies, RF front-end transmitters are also developing in the direction of multi-frequency, multi-mode, high efficiency, high gain, and high power output. Therefore, the market urgently needs multi-frequency multi-mode, high-efficiency, high-gain, high-power power amplifiers. However, in the design of traditional high-efficiency power amplifiers, there have always been some design problems, mainly reflected in the difficulty of multi-frequency and multi-mode mutual constraints when compatible with high-efficiency ind...
