Design and Simulation of RF Front End Receiver Mixer for 5G NR Application

The need for new technologies to handle peak high speed data rates for the aforementioned communication benefits has unquestionably grown exponentially over the last few years. In this paper, a receiver RF front end mixer design operating for 5G NR application. The BJT transistor with part number BFP405F is selected for the down conversion mixer design. Transistor is biased and check for the stability at the given frequency. Matching circuit is designed for the transistor to obtain the better conversion gain and return loss. The input RF and LO frequencies are 3.5 GHz and 3.3 GHz, respectively, with input power -10 dbm at LO path. The output frequency obtained at the IF is 200 MHz. The designed active down conversion mixer is simulated in ADS. The desired mixer has good linearity, a modest conversion gain, and good return loss. Conversion gain for the designed down conversion mixer is +5.03 dB.
