Abstract

The invention relates to an eight-unit T/R (transmitting/receiving) basic module with a function of S-band multi-beam transceiving duplexing, applicable to large-scaled multi-beam active phased-array radar, especially S-band unified carrier measurement and control communication systems, and belongs to the technical field of microwave and millimeter wave communications. The module runs under the band of 2.0-2.3GHz and comprises an eight-circuit T/R unit, two one-to-eight power dividers, four combiners and a digital control unit. The module runs under the S-band; a double-channel high-suppression duplexer is used to suppress leakage of transmitted signals, a sideband interval of the transmitting band and the receiving band is only 80MHz for a transceiving duplexing system, and the transmitted signals can be prevented from jamming a preamplifier of a receiving branch even when output power of transmitted beams is up to +20dBm (1W).

Description

technical field [0001] The invention relates to an eight-unit T / R basic module of S-band multi-beam transceiving duplex, which is suitable for large-scale multi-beam active phased array radar, especially the S-band unified carrier measurement and control communication system, and belongs to the technical field of microwave and millimeter wave communication . Background technique [0002] In an active phased array radar, the number of T / R components ranges from dozens to tens of thousands. It has both a transmitting channel and a receiving channel, and has functions such as phase shifting and beam control. Therefore, the T / R component is one of the core components of the active phased array radar, and its performance, reliability, and development cost will directly affect the success or failure of the system. [0003] In order to meet the requirement of low sidelobe, the T / R component must adapt to the unit spacing requirement of the antenna less than 0.5λ. At the same time,...
