Embodiment 1

[0033] Embodiment 1, the number of grooves 102 is four symmetrically distributed in parallel, the number of radio frequency channels 108 is also four, the partition wall 103 is distributed between each groove 102 in a cross shape, and the lumped circuit 105 is located in the partition wall At the center of 103 , the electrical lengths of each radio frequency channel 108 and the microwave transmission line 104 of the lumped circuit 105 are equal, so that the insertion loss is consistent. The cavity of the partition wall 103 constitutes a multi-channel structure, and the microwave transmission lines 104 are distributed along the structure direction of the cavity of the partition wall 103 , making full use of the three-dimensional space formed by the partition wall 103 . With this structure, a relatively closed cavity is formed inside the partition wall 103, and the radio frequency coaxial hole and the strip line of the microwave transmission line 104 are arranged in the cavity of...

Embodiment 2

[0034] In Embodiment 2, several grooves 102 are provided and distributed evenly in a circular shape, and the number of radio frequency channels 108 is the same as the number of grooves 102 . The partition wall 103 extends outward until it touches the inner wall of the substrate 101, thereby separating each groove 102, and the lumped circuit 105 is located at the center of the partition wall 103, so that each radio frequency channel 108 and the lumped circuit 105 are connected The electrical lengths of the microstrip lines 104 are equal. Similar to Embodiment 1, the microwave transmission line 104 and the mains transmission line 109 in this embodiment are also arranged along the structural direction of the partition wall 103, making full use of the internal space of the T / R assembly.

[0035]The upper surface and the lower surface of the partition wall 103 are provided with a metal film layer, and the upper surface and the lower surface are used for laying the microwave transmi...

Abstract

The invention discloses a multi-channel surface-mounted T / R assembly in the field of radio frequency microwave assemblies, which comprises a substrate, the upper surface of the substrate is fixedly connected with a metal ring frame, and the upper part of the metal ring frame is fixedly connected with a cover plate; the upper surface of the substrate is also provided with a plurality of grooves which are regularly distributed, radio frequency channels are arranged in the grooves, the radio frequency channels are electromagnetically isolated by partition walls among the grooves, and the partition walls and the substrate are made of the same material; an inner cavity is formed in the partition wall, and a microwave transmission line is arranged in the inner cavity; and a lumped circuit is further arranged on the substrate, one end of each radio frequency channel is connected to an antenna port of the T / R assembly, the other end of each radio frequency channel is connected to a branch port of the lumped circuit through a microwave transmission line, the electrical length of each radio frequency channel is equal to that of the microwave transmission line of the lumped circuit, and a total port of the lumped circuit is connected to a lumped port of the T / R assembly through a total port transmission line. According to the invention, a multi-channel comprehensive integrated structure is adopted, the usage amount of metal materials is reduced, the internal space of the T / R assembly is fully utilized, and the effects of miniaturization and light weight are achieved.

Description

technical field [0001] The invention relates to the field of radio frequency microwave components, in particular to a multi-channel surface mount T / R component. Background technique [0002] As the core of active phased arrays, T / R components are widely used in communication and radar systems. The T / R component is a necessary component for active phased array radar to realize fast electrical scanning, digital beam forming and spatial power combining, and its performance will have a decisive impact on the performance of the whole machine. [0003] The development of phased array technology has higher and higher requirements for T / R components, which are manifested in: T / R components are required to be miniaturized, lightweight, highly reliable, and high-power. This development requirement brings many difficulties to the design and manufacture of T / R components. The miniaturization of T / R components makes microwave signals not only distributed on the surface of the substrate...
