| Abstract: | By presenting the VHF frequency-hopping radio receiver front end,based on the RF design and simulation software ADS by Agilent,this paper makes a receiver front-end RF circuit simulation and circuit design.A RF front-end circuit model composed of a protection circuit,pre-filter,low-noise amplifier and automatic gain control circuit is constructed and simulated.The final results show that the RF front-end in this paper meets the requirements for the system and is improved to some degree. |
