Research and Design of a Large Bandwidth Receiver RF Front-End

Abstract:

RF front-end is an important part of the communication system. It realizes the functions such as low noise amplifier application, filtering and mixing, completes the conversion between the IF signal and the RF signal, and ensures effective communication system flexibility and versatility. In the paper, according to the superheterodyne structure, a receiver RF front-end has been designed. The total gain of the link circuit is more than 100 dB, with 50 dB AGC range, the center frequency is 750 MHz with 100MHz bandwidth, local oscillator (LO) signal with frequency 935MHz is generated by PLL and the stability is-82dBc/Hz@1KHz.
