Versatility Miniaturization Of The Receiver Front-end Design

In the current aviation technology advances, installed equipment, aviation platforms increasing space, weight, power requirements and platform navigation speed, endurance time of great contradictions, aviation equipment, universal, strong demand for compact design. This research is a kind of versatility FM aeronautical communications equipment, which has data and voice transmission capabilities, integrated a variety of work and modulation, has good versatility and scalability. This paper focuses on the equipment front end module receives the versatility and compact designIn the receiver front-end module design, in order to meet the general requirements, from the signal gain, channel bandwidth, AGC response time and other aspects to consider a different modulation of the signal on the channel's different needs, and make a difference in design; in small design, the integrated device as far as possible, so that the product size, weight above has improved significantly, and has been fitted out in a pre-air communications equipment receiver module size reduction compared to more than one third; the same time, integrated device the extensive use of technical state of the product consistency has greatly improved the product significantly reduces the complexity of debugging.
