Design and Application of High Frequency Amplifier in the VHF Frequency-hopping Radio Receiver
Wu Xinbao · Journal of Hangzhou Dianzi University · 2010
VHF frequency-hopping radio played an important role in the military communications,it can to ensure that the anti-jamming communications and covert. Wireless communications receiver is main part of the frequency-hopping radio channel,the high frequency amplifier is an important part of the wireless communications receiver,and a critical components of receiver to achieve dynamic performance.A receiver design concept to the new generation of VHF frequency-hopping radio is made,the design process of high frequency amplifier is given,the design of high frequency amplifier frequency-hopping digital filter is focused on.Combination of hardware circuit to analysis circuit functions.Results by the test,the system performance indicators to meet the design requirements,obtain good results in practical applications.
