Large Bandwidth Channelized RF Receiver Based on Chirped Pulses Mixing

Abstract

For military and civilian applications, the ultra-wideband Radio Frequency (RF) receiver is in great demand. As the development and requirement in near future, a very receiver which can handle frequency carrier ranging tens of GHz is urgently desired [1]. Also considering that the electronic circuit receiver combined a mixer and analog to digital converter(ADC) has to filtering the extra signal at the back end [2], it is essential to provide a means to channelize the broadband signal spectrum into frequency channels of which bandwidths are compatible with digital electronics [3].
