射频接收机 meaning in English
video receiver
Examples
- Tuned radio - frequency receiver
调谐式射频接收机 - For satisfying the requirement of sampling rate and sampling precision about rf receiver , in this dissertation , we design and constructed a high - speed and high - precision data acquisition system working at 90 mhz sampling frequency
为了满足射频接收机对前端数据采集的速率和精度要求,本文设计并研制了一种基于ad6645的高速数据采集模块,经测试证明模块的性能完全满足接收机的要求。 - This problem could be resolved by using sub - harmonic mixer ( shm ) . instead of using mmw lo , shm using microwave signal with frequency equals 1 / 2 or 1 / 4 of mmw lo frequency , thus the technical difficulty and cost of mmw system is reduced remarkably
采用亚谐波混频器( sub - harmonicmixer )可将本振频率降为基波频率的1 / 2或1 / 4 ,从而克服了直接采用毫米波本振源带来的困难,降低了射频接收机的技术难度和系统成本。 - The first chapter , introduce the rf receiver ’ s devolop and current situation . the second chapter , introduce the effect of the exterior environment to the rf receiver . the third chapter introduce some different structure and the design parameters of each structures . the parameters of the rf receiver are introduce in fourth chapter . the fifth chapter design a s band rf receiver . this s band rf receiver use a structure of superheterodyne module
第五章,介绍了一种s波段射频接收前端的设计,基于分析的结果对一种射频接收机的低噪放大、下变频、锁相环( pll )频率合成器、中频agc电路进行了设计,并在第六章完成了接收机各组件及总体的测试。 - The subject comes from the cooperation project “ long distance navigation short - wave receiver ” between chengdu sine science & technology ltd . and automatization school of harbin engineering university . the auther was responsible for implementation of the rf receiver of the system . the rf receiver consists of a rf front end , 3 dds synthesizer
