Abstract

The invention discloses a multi-chip integration E band receiving module which comprises an upper metal base and a lower metal base, a medium-frequency low-pass filtering circuit, and a local oscillator circuit and a down-conversion structure are respectively arranged in a cavity formed by the upper metal base and the lower metal base. A medium-frequency input end adopts a standard subminiature version A (SMA) connector, a local oscillator input end is of a standard waveguide flange structure, and the radio frequency output end is of a standard waveguide flange structure. Signal coupling between the waveguide and microstrip circuits of the module is achieved through a transitional structure, and a low-loss substrate circuit is connected with various functional gallium arsenide chips electrically. Based on the multi-chip integration technology, the multi-chip integration E band receiving module has the advantages of being compact in structure, high in integration degree, low in cost, good in consistency and convenient to manufacture in a large-scale mode.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a multi-chip integrated E-band receiving module. Background technique [0002] Microwave is a common wireless communication technology. It is widely used in the relay and backhaul of various communication systems due to its long-distance, large-capacity, fast deployment, and strong anti-loss characteristics. With the continuous demand for mobile broadband, the conventional 6GHz~38GHz microwave spectrum resources have been quickly exhausted, and the expansion of microwave communication to higher frequency bands has become an inevitable trend. E-band microwaves were released by the International Telecommunication Union (ITU-R) in 2001 and 2003. They mainly include high-frequency microwave communications at 60GHz and 80GHz. The 60GHz free frequency band was earlier used by military and industrial customers. For businessmen, the 80GHz microwave frequency band will...
