A bottom plate, a cover plate, a front plate, a rear plate, a left plate and a right plate are used as walls to form a mounting cavity; the method is characterized in that n groups of first connectors are mountedon the bottom plate, wherein each group of first connectors consists of a receiving connector and a transmitting connector, each group of first connectors are respectively vertical to the bottom plate, a group of second connectors are arranged on the cover plate, the second connectors are combination ports for receiving output and transmitting input, a through groove is arranged on the cover plate, and three layers are arranged in the mounting cavity. According to the invention, multiple radio frequency channels are integrated to realize miniaturization, the profile height of the active phased-array antenna can be effectively reduced, and a heating device in the T / R assembly clings to the heat sink to achieve the purpose of rapid heat conduction.

Description

technical field [0001] The present invention relates to the field of aerospace, and more specifically, relates to a highly integrated multi-channel tiled T / R assembly, an active phased array antenna and an arrangement method for a highly integrated multi-channel tiled T / R assembly. Background technique [0002] Active phased array antennas have been widely used in military and civilian fields such as radar and communications. The T / R component is the most critical component of this type of antenna. The RF signal direction of the traditional brick-type T / R component is parallel to the component installation direction, which has the advantages of simple circuit, mature technology and low cost. However, on the one hand, as the operating frequency increases, the element spacing of the active phased array antenna becomes very small. Generally, the array element spacing is about half the wavelength of the frequency. When the operating frequency is 1GHz, the array element spacing i...

Problems solved by technology

However, on the one hand, as the operating frequency increases, the element spacing of the active phased array antenna becomes very small. Generally, the array element spacing is about half the wavelength of the frequency. When the operating frequency is 1GHz, the array element spacing is about 150mm. When the operating frequency is increased to 10GHz, the array element spacing is about 15mm, resulting in a very thin brick component, which is even difficult to realize in engineering; on the other hand, the component is far away from the cold plate, the heat dissipation path is long, the thermal resistance is large, and the heat dissipation structure is complicated.

At the same time, the installation method determines its large longitudinal size, which makes it difficult to reduce the profile of the entire active antenna, and is not suitable for active phased array antenna applications with low profile requirements such as limited space size, special loading platforms, or conformal arrays.
