Abstract

The invention provides a miniaturized low-cost high-dynamic-range receiving and amplifying assembly. The assembly comprises a first horizontal polarization signal input port, a first vertical polarization signal input port, a second horizontal polarization signal input port, a second vertical polarization signal input port which are sequentially arranged, a first combiner which is electrically connected with the first horizontal polarization signal input port and the second horizontal polarization signal input port, a first receiving amplification link and a first signal output port which areelectrically connected with the first combiner in sequence, a second combiner which is electrically connected with the first vertical polarization signal input port and the second vertical polarization signal input port, and a second receiving and amplifying link and a second signal output port which are electrically connected with the second combiner in sequence. The invention provides a receiving and amplifying assembly which is small in size, low in cost, high in dynamic range and capable of achieving four-input two-output of a receiving channel. A vertical interconnection structure is flexibly adopted, port and transmission line layouts are reasonably designed, a combiner is adopted to realize sharing of circuits of a receiving part, and a receiving link adopts a double-switch mode.

Description

technical field [0001] The invention relates to the technical field of electrical communication, in particular to a miniaturized, low-cost and high dynamic range receiving amplifier assembly. Background technique [0002] The receiving antenna has a large field of view and a wide frequency band, which can effectively detect most of the transmitting equipment within the detection range. The receiving amplification component located at the front end of the receiving antenna is one of the core components of the receiving antenna, and its input port is connected to the receiving The antenna array and the output port are connected to the channel, which plays a key role in linking the past and the future. Realize the reception synthesis, filtering, amplification and other functions of the receiving antenna. The receiving and amplifying component is in a key position in the receiving antenna, and plays a decisive role in the performance of the entire receiving antenna. Since the r...
