Description

Technical Field
The utility model relates to a field effect transistor radio frequency power amplifier and integrated circuit field, especially to the synthetic power amplifier of a high power double difference vary voltage that the terminal emission module of radio frequency microwave transceiver used.
Background
With the rapid development of wireless communication systems and rf microwave circuits, rf front-end transceivers are also developing in the direction of high performance, high integration, and low power consumption. Therefore, the rf and microwave power amplifiers of the transmitter are urgently required to have high output power, high gain, high efficiency, low cost and other performances in the market, and the integrated circuit is a key technology expected to meet the market demand.
However, when the integrated circuit process design is adopted to realize the chip circuit of the radio frequency and microwave power amplifier, the performance and the cost are limited to a certain extent, and the method mainly comprises the following steps:
(1) high power, high efficiency capability is limited: the traditional power amplifier adopts a multi-path parallel synthesis structure or a distributed structure, the synthesis efficiency of the two structures is limited, a part of power is lost in a synthesis network, and the high-power and high-efficiency capability is limited.
(2) Low power consumption, high gain amplification capability is limited: the power amplifier of the traditional single-ended common-source transistor is influenced by parasitic parameters of the transistor, has lower gain when working at high frequency, is greatly limited in power capability, and has higher difficulty in realizing low power consumption.
The circuit structures of common high-gain and high-power amplifiers are many, most typically, a multi-stage and multi-path synthesis single-ended power amplifier, but it is very difficult for a conventional multi-stage and multi-path synthesis single-ended power amplifier to simultaneously meet the requirements of various parameters, mainly because:
① the output impedance of the traditional multi-stage, multi-path synthesis single-ended power amplifier is low when it adopts multi-path parallel synthesis structure, therefore the output synthesis network needs to realize the impedance matching of high impedance transformation ratio, which often needs to sacrifice the gain of the amplifier and reduce the power, thus limiting the high power and high efficiency capability.
② in the traditional amplifier based on the active transformer synthesis network, the amplifier unit usually adopts a single-stage common-source amplifier or a Cascode amplifier, but the gains of the two amplifiers are relatively limited, and the output power is relatively limited by a single tube.
Therefore, the design difficulty of the high-gain and high-power amplifier based on the integrated circuit process is as follows: high power and high efficiency output difficulty is large; the traditional single transistor structure or the multiplex synthesis structure of Cascode transistors has many limitations in amplifiers based on active transformer synthesis networks.
