Embodiment Construction

[0041] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0042] Such as figure 1As shown, it is a functional block diagram of an embodiment of the four-channel radio frequency transmitting module of the present invention. The radio frequency signal enters the first driving stage amplifier 1 through the input terminal, and after being amplified by the first driving stage amplifier 1, it is sent to a power dividing network 2 divided into four, and one radio frequency signal is divided into four routes, and each route is digitally phase-shifted attenuator 3 , the second push stage amplifier 4, the final stage amplifier 5 and the transmitting antenna 6 form a transmitting channel, respectively forming the transmitting ...

Abstract

The invention discloses a radio-frequency transmitting module, a radio-frequency transmitting component, a phased-array antenna and a production method thereof. The radio-frequency transmitting module comprises a first drive stage amplifier, a power dividing network, four transmitting channels, a power module and a wave control microwave daughter board, the radio-frequency transmitting component is formed by the lamination of two radio-frequency transmitting modules which are face-to-face and mirror images of each other; and the phased-array antenna is combined by fixing eight or an integer multiple of eight radio-frequency transmitting modules in a shell in parallel. According to the radio-frequency transmitting module, the radio-frequency transmitting component, the phased-array antenna and the production method thereof, the power amplifiers at various stages are all realized by ultra-broadband power amplifier chips, the chip utilizes a low-voltage power supply, the cost is low, the nonlinear characteristic is good, and the power synthesis is conveniently realized.

Description

technical field [0001] The invention relates to a high-frequency transmitting device, in particular to a radio frequency transmitting module, component, phased array antenna and a manufacturing method thereof based on an ultra-wideband power amplifier chip. Background technique [0002] The existing microwave transmitting components are large in size, large in power consumption, high in mass, simple in function, low in circuit integration, and low in operating frequency. They basically work in, for example, C-band, X-band and Ku-band, etc., which cannot meet the needs of radar. And the requirements for the continuous improvement of the operating frequency of electronic countermeasure equipment. [0003] For example, the Chinese utility model patent "Ku-band 4-channel transmitting assembly" with the authorized announcement number CN203299374U discloses a 4-channel transmitting assembly working in the Ku-band. It has no modularization, and each transmitting channel cannot be i...
