A single-stage down conversion superheterodyne receiver was designed, simulated and analyzed using Electronic Design Automation (EDA) software. Depending on the Dynamic Range (DR) requirements and Noise Figure (NF) requirements, the gains of the LNA were adjusted so as to enable the receiver to have maximum DR and minimum noise figure. The receiver was then modeled on the EDA simulator using the in-built components available. All the parameters were set as per the requirements and then the model was simulated. The data obtained from the simulation was analyzed by using the data display screen where any kind of plot (rectangular, polar, smith chart or tabular list, etc.) can be plotted for the data available.

A receiver is a circuit used in a communication/radar system to receive the information or data signal that has been transmitted by a transmitter. Transmitting a signal of some frequency is easier compared to receiving a desired signal out of a many noise signals and undesired (spurious) signals. The performance of any communication/Radar system is dependent largely on the efficiency of the receiver used in it. This is the reason why receiver design became a very important and complex stage in the communication system designing. The main intention behind using a communication system is to communicate or transfer information from one point in space to another point. In such a system, if the receiver is not efficient and does not pick up the desired signals efficiently, then the entire purpose of using a communication system is lost. Day-by-day, numerous techniques are being invented for efficient transmission of data, and accordingly, the receiver configurations are also changing. The basic principles behind the receiver remain unchanged, but when more and more specifications are to be met, the constraints on the design of the receiver become more and more. In order to design a receiver with any level of complexity, we must be very strong with the basic principles behind the receiver working and its design.

We must also identify the potential areas where we generally face difficulties in the design process.
