Abstract

The invention discloses a dual-channel transmitting assembly for a phased-array antenna of a carrier rocket relay user terminal. The dual-channel transmitting assembly comprises a first channel radiofrequency circuit and a second channel radio frequency circuit, wherein the first channel radio frequency circuit comprises a first channel numerical control phase shifter, a first channel driving amplifier, a first channel power amplifier, a first channel microstrip directional coupler, a first channel single-section isolator and a first channel detection diode connected with the first channel microstrip directional coupler, which are connected in sequence; and the second channel radio frequency circuit comprises a second channel numerical control phase shifter, a second channel driving amplifier, a second channel power amplifier, a second channel microstrip directional coupler, a second channel single-section isolator and a second channel detection diode connected with the second channelmicrostrip directional coupler which are connected in sequence. Compared with a single-channel phase-shifting transmitting assembly, the phased-array antenna transmitting assembly is compact in structure, the array area of a phased-array antenna can be reduced, and the weight of the whole phased-array antenna is reduced.

Description

technical field [0001] The invention belongs to the technical field of microwave circuits, and in particular relates to a dual-channel transmitting assembly used for a carrier rocket relay user terminal phased array antenna. Background technique [0002] With the completion and use of my country's relay satellite system, the conditions for the launch vehicle to use space-based measurement and control technology to conduct full-course measurement and control of the flight have matured. This will greatly improve the shortcomings of traditional ground-based measurement and control technology that cannot meet the coverage of measurement and control and the real-time performance of data transmission. [0003] The space-based measurement and control system of the launch vehicle uses an active phased array antenna, which will benefit the conformal design of the rocket body. At the same time, the fast beam scanning capability of the phased array antenna will also greatly enhance the...
