Abstract

The invention discloses a multi-chip integrated E-band transmitting module which comprises an upper metal base and a lower metal base. A medium-frequency low-pass filter circuit, a local oscillator circuit and an up-conversion circuit are respectively disposed in a cavity formed by the upper metal base and the lower metal base. A standard SMA (shape memory alloy) connector is arranged at a medium-frequency input end. A local oscillator input end is in a standard waveguide flange structure. A radiofrequency output end is in a standard waveguide flange structure. Signal coupling between a waveguide and a microstrip circuit in the module is achieved through a transition structure, and a low-loss substrate circuit and functional gallium arsenide chips are electrically connected by gold wire bonding. The multi-chip integrated E-band transmitting module based on multi-chip integration technology has the advantages of compact structure, high integrity, low cost, high uniformity and convenience in large-scale manufacturing.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-chip integrated E-band transmitting 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 damage resistance. With the continuous mobile broadband bearer demand, conventional microwave spectrum resources from 6GHz to 38GHz have been rapidly exhausted, and it has become an inevitable trend for microwave communication to expand to higher frequency bands. The E-band microwave was released by the International Telecommunications Union Radio Organization (ITU-R) in 2001 and 2003, mainly including 60GHz and 80GHz high-frequency microwave communications. The 60GHz free frequency band was earlier used by the military and industry customers. For business operators, the 80GHz microw...
