Embodiment Construction

[0016] like figure 1 As shown, a detection and communication integrated TR component adopts a four-channel design, and is composed of four identical transceiver channels 1 and a four-power divider 2 . One end of the four transceiver channels 1 is an antenna interface, which is connected to the antenna unit, and the other end is a power splitter interface, which is respectively connected to the first port, the second port, the third port and the fourth port of the four power splitter 2, a total of four power splitters port. The four-power splitter 2 has five ports in total, the first port, the second port, the third port and the fourth port are power splitting ports, receiving and sending channels; the fifth port is a common port, connected to the back-end circuit.

[0017] like figure 2 As shown, the transceiver channel 1 is composed of a circulator 3 , a receiving branch, a linear low-power transmitting branch, a saturated high-power transmitting branch and a transmitting ...

Abstract

The invention relates to a detection and communication integrated TR assembly, which comprises four receiving and transmitting channels 1 and a four-power divider 2, wherein each receiving and transmitting channel comprises a circulator 3, a receiving branch, a linear low-power transmitting branch, a saturated high-power transmitting branch and a receiving and transmitting switch 5, the receiving branch comprises an amplitude limiting low-noise amplifier 4, the linear low-power transmitting branch comprises a numerical control attenuator 6, a driver 7, a first switch 8 and a second switch 10, and the saturated high-power transmitting branch comprises the numerical control attenuator 6, the driver 7, the first switch 8, a power amplifier 9 and the second switch 10. According to the invention, while a low-noise receiving function is realized, compatible integration of a linear low-power transmitting function and a saturated high-power transmitting function is realized by two measures of controlling the input power of the driver 7 and the switch selection power amplifier 9 to work through the numerical control attenuator 6.

Description

technical field [0001] The invention relates to the technical field of phased array arrays, in particular to a T / R assembly used for detection and communication multifunctional integrated phased array equipment. Background technique [0002] Multifunctional integrated phased array equipment integrates multiple functions such as radar, communication, and electronic warfare into one phased array equipment, thereby greatly improving system integration, equipment utilization and work efficiency. It is the current phased array technology an important direction of development. The TR component is used for sending and receiving signals of each antenna unit of the phased array, and is an important component of the phased array equipment. Due to the different working mechanisms of different functional tasks, the functional characteristics and performance parameters of the required equipment are also different, thus putting forward different requirements for TR components. For radar...
