Abstract

The super heterodyne receiver is employed to receive signals at any frequency. A Mixer is an integral block of super heterodyning reception. It down converts the received signal at RF frequency to IF frequency. In this paper, a single ended double balanced Gilbert mixer is designed. This is matched internally to 60 ohms and is operated at a 900 MHz frequency, which is the band frequency of amateur radio (UHF) Spectrum. The circuit of this mixer is simulated and analyzed to find the conversion gains, spectral analysis of the input and output frequencies (IF & RF).
