Microstrip 5G Receiver Design & Simulation

This paper explains the design and simulation of a 28 GHz microstrip receiver front end for 5G, with a custom-designed radio frequency (RF) filter, an intermediate frequency (IF) filter and a low-noise amplifier (LNA). The input signal first travels through two stages of LNA, then the RF filter leaves the 28.943 GHz component while filtering out the rest of the frequencies. In the next stage, the signal goes into a commercial IC from Analog Devices, and it is multiplied by the frequency of the local oscillator to mix the centre frequency down to 1 GHz. For the final stage of the receiver, the IF bandpass filter is designed to let the lGHz frequency pass while filtering out the rest. This receiver design is based on microstrip technology, and the simulation results proves that it satisfies the intended functions.
