The demand for new technologies so as to meet peak high speed data rates for enumerated communication perks have surely seen an exponential growth in past few years. In this paper, a system design of receiver RF front end has been designed lying in the frequency range used in 5G applications (sub 6 GHz) of 3.3-3.7 GHz centered at 3.5GHz. The cascaded system comprises of a Low Noise Amplifier having gain of 15dB cascaded with a Band Pass Filter with 1dB insertion loss, that is being fed to one of the input port of power combiner, whereas a Local Oscillator having 3.5GHz as its signal frequency is fed to the other port. The output is then fed to a single diode Mixer that avoids the need of RF and LO baluns with return loss of less than -30dB in RF, LO and IF ports. Overall simulated system gain is 7.916dB. The devices so used in LNA, Oscillator and Mixer are HMC-C022, ATF13786 and HSCH5310 respectively. The proposed circuits realized using microstrip lines in Advanced Design System.
