Abstract:

RF mixer is an essential part of wireless communication system, modern wireless communication systems demand stringent dynamic range requirements. The dynamic range of a receiver is often limited by the first down conversion mixer. This forces many compromises between figures of merits such as conversion gain, linearity, dynamic range, noise figure and port to port isolation of the mixer. Integrated mixer more desirable than discrete one for higher system integration with cost and space savings. In order to optimize the overall system performance, there exists a need to examine the merits and shortcoming of each mixer feasible for integrated solutions. An ISM band (2.45 GHz) down conversion mixer has been designed and simulated in tanner tool. The local oscillator frequency is at 3.15 GHz. the mixer's lower sideband frequency is 700 MHz with amplitude of 1.4 v.the mixer provides a conversion gain of 8.9 dB the detail methodology and simulation results are presented in this paper.
